wcslib-5.18-bp151.3.1

- Update to version 5.18:
  * C library
  - New routines introduced to preclude altering the global
    variables NPVMAX, NPSMAX, and NDPMAX, which determine how
    much memory to allocate for storing PVi_ma, PSi_ma, DPja, and
    DQia keyvalues: wcsinit(), lininit(), lindist(), and
    disinit().  These are now used by various WCSLIB routines,
    such as the header parsers, which previously temporarily
    altered the global variables, thus posing a thread hazard.
  - The Flex scanners, fitshdr(), wcsbth(), wcspih(), wcsulexe(),
    and wcsutrne(), have been rewritten as thin wrappers (with
    the same API) over scanners that were modified (with changed
    API) as required to use Flex's "reentrant" option.
    Consequently, they are now reentrant and should be
    thread-safe.  That also passes through to the deprecated
    wrappers, wcsulex() and wcsutrn().
  - Fixed memory leaks in lindist() and lincpy() uncovered by
    valgrind.
  - Test programs tfitshdr, tpih1, tpih2, and ttab3 are now
    careful to free all allocated memory before exit to defeat
    spurious reports of memory leaks by valgrind.
  * Fortran wrappers
  - New wrappers for wcsinit(), lininit(), lindist(), and
    disinit().
  * User manual
  - Updates and amendments in line with the above changes.
  - Documentation generation moved to doxygen 1.8.14
    (was 1.8.13).
  From version 5.17:
  * C library
  - Fixed a memory leak in wcspih().
  - Fixed compiler warnings about comparison between signed and
    unsigned integers in tab.c. Also fixed warnings in other
    functions about unused parameters.
  * Fortran wrappers
  - Fixed compiler warnings about comparison between signed and
    unsigned integers in several routines.
  * PGSBOX
  - Fixed a compiler warning about comparison between signed and
    unsigned ints.
  * Installation
  - Removed setgid permission on installation directories.
  * User manual
  - Minor updates and amendments.
  - Documentation generation moved to doxygen 1.8.13 (was
    1.8.10).

- Update to version 5.16:
  * C library
  - Bug fix in spcfix() for the previous change.

- Rename the package from libwcs to wcslib. Added appropriate
  Provides/Obsoletes entries.

- Avoid unnecessary double emittance of %optflags into compiler
  line. Fixup groups for openSUSE Factory acceptance.

- Removed static library.
- Removed requirement of libwcs lib from libwcs-doc (not needed).
- Added Recommends entry for libwcs-doc in libwcs-devel.

- Update to version 5.15:
  * C library
  - Bug fix in wcsulex.l for the previous change.  Reported, and
    fix supplied by Tammo Jan Dijkema.
  - In spcfix(), report the value of VELREF if ctype is
    translated from the AIPS convention.
  From version 5.14:
  * C library
  - In wcsulex.l and wcsutrn.l, applied a workaround for a memory
    leak introduced by a change (bug) in flex in Aug/2012.
    Reported, and fix supplied by Thomas Robitaille and Erik
    Bray.
  * Installation
  - In MacOSX, create symlink libwcs.dylib pointing to the
    dynamic library so that WCSLIB is linked dynamically by
    default. Requested by Paul Price.

- Update to version 5.13
  * C library
  - In wcshdo(), provide floating-point format control via the 'ctrl'
    argument (formerly 'relax').
  - In wcspih(), PLATEID by itself is no longer sufficient to trigger a
    DSS translation (reported by James Allen).
  - In unitfix(), ensure that the message buffer cannot be overrun, e.g.
    by blank-padded unit strings (reported by Vishal Kasliwal).
- Update to version 5.12
  * C library
  - Bug fix in wcshdo() for CRVALia precision reported by Mihai Cara.
- Update to version 5.11
  * C library
  - Bug fixes in wcspih.l and dis.c for WAT distortions provided by
    Ole Streicher.
- Update to version 5.10
  * C library
  - In wcshdo(), allow output of floating point keyvalues to 15
    significant digits (was 14), mainly for astropy.
  - In wcspih(), allow unrecognised WAT projection types (tan, etc.) to
    pass without returning an error.  Reported by Michael Droettboom.
    Also fixed a bug triggered by SIP keywords in unconventional order,
    reported by Colin Slater, LSST.
- Update to version 5.9
  * C library
  - In disx2p(), make proper allowance for the possibility that the TPD
    and SIP forward and inverse distortion polynomials may not be of the
    same degree, reported by Martin Kuemmel.
  - Fix-ups in wcshdo() reported by Michael Droettboom, and several
    tidy-ups as well.
- Update to version 5.8
  * C library
  - DSS (Digitized Sky Survey) coordinates are now handled via TPD, as
    are the TNX and ZPX "projections".  New test script tdis3 and
    headers DSS.keyrec, TNX.keyrec, and ZPX.keyrec.
  - New function dishdo() can be used to set a flag that causes
    wcshdo() to write headers in the form of the distortion function
    used internally (usually TPD).
  - Added the capability, via DPja.DOCORR, for a distortion function to
    to compute an additive correction to the undistorted coordinates
    (rather than computing the distorted coordinates themselves).
  - Added auxiliary variables to TPD via DPja.AUX.jhat.COEFF.m.
  - Bug fix in wcshdo() for TPV, diagnosed by Michael Droettboom.
  * Fortran wrappers
  - Wrapper for dishdo().
- Update to version 5.7
  * C library
  - Extended wcssub() to handle distortions (and thus wcscopy() also).
    This required axis mapping to be enabled for SIP distortions within
    WCSLIB.
  - wcshdo() now handles all distortions currently supported by WCSLIB:
    SIP, TPV, TPD, and Polynomial.
  - Bug fixes in sphx2s() and sphs2x() for non-unit vector strides for
    special-case rotations.
  - In wcsset(), modify wcsprm::ctype after translating TPV so that
    subsequent calls won't try to re-translate it, the PVi_ma records
    by then having been erased.  Reported by Michael Droettboom.  Also,
    restore NDPMAX after translating TPV.
  - Bug fixes in discpy(), disprt(), disset(), and disx2p().
  - Added disperr(), prjperr(), spcperr(), spxperr(), and tabperr() to
    complete the set and make reporting errors slightly more convenient.
  * Utilities
  - wcsware has a new option, -o, to print the wcsprm struct in the form
    of a FITS header using wcshdo().  Also, the -a option has been
    extended to allow a 0-relative numeric index for selecting an
    alternate WCS, where the alternates are sequenced alphabetically
    (without gaps) following the primary representation.
  * User manual
  - Documentation generation moved to doxygen 1.8.10 (was 1.8.9.1).
- Update to version 5.6
  * C library
  - Bug fixes in wcspih() and sipset() to account for the fact that the
    independent variables of the SIP polynomial are pixel coordinate
    offsets from CRPIXja, not pixel coordinates per se.  Diagnosed by
    Michael Droettboom.
  - Validated SIP and TPV handling by comparing the output of
    'wcsware -x' with that of wcstools 'xy2sky -d -n6' using astropy's
    SIP test headers, and separate SIP and TPV headers originating from
    the Palomar Transient Factory provided by David Shupe.
  - Changed SIP.keyrec so that CRPIX1 and CRPIX2 differ in value,
    thereby making tests sensitive to any confusion between the two.
- Update to version 5.5
  * C library
  - Bug fixes in wcspih.l for headers with multiple distortions, and for
    distortion parameter look-alike keywords.
  - Bug fix in sipset() uncovered by valgrind.
- Update to version 5.4.1
  * C library
  - Added a fairly lengthy section to the prologue of dis.h describing
    the Paper IV keywords and the distortion functions currently
    implemented.
  * User manual
  - Added a new section on WCSLIB version numbers.
- Update to version 5.4
  * C library
  - Further work on distortions: wcspih() now parses Paper IV distortion
    keywords (CPDISja, CQDISia, DPja, DQia, etc.), thus handling record-
    valued keywords.  SIP keywords are also parsed and translated into
    Paper IV keywords.
  - TPV, SIP, and whereever possible, the general Polynomial distortion
    function of Paper IV are now implemented by the Template Polynomial
    Distortion (TPD), that being a superset of TPV and SIP.  TPD, which
    can also handle 1D distortions and be used for inversions, is also
    supported as a separate distortion type defined by Paper IV
    keywords.  TPD efficiently handles 1D distortions and distortions
    without radial terms.
  - Specialized inverse distortions, such as defined by SIP, are
    implemented by TPD and recognized by disx2p(), which uses them to
    compute the initial approximation of its more precise iterative
    solution.
  - Generalized tdis1.c so that it can do closure tests for SIP headers,
    and added a SIP test header.
- Update to version 5.3.1
  * C library
  - Bug fix in test program tdis1.c reported by Martin Kuemmel.
- Update to version 5.3
  * First public release of WCSLIB 5.x with distortions capability.
  * C library
  - Changed disprm::dtype from char[16] to char[72] for reasons relating
    to header parsing.
  - More armour plating for disset() and friends.  They also use new
    utility functions wcsutil_dpkey_int() and wcsutil_dpkey_double() to
    extract numeric values from a dpkey struct.  This ensures their
    independence of the data type, the appropriate reporting of dpkey
    values by disprt(), and (eventually) the appropriate writing of DPja
    and DQia keyvalues by wcshdo().
  - Augmented the usage comments for dpfill() to explain how numeric
    values in a dpkey struct are handled.
  * Utilities
  - wcsware now uses wcserr to provide a backtrace on errors.  Also
    fixed a couple of minor annoyances relating to alternate
    representations.
- Update to version 5.2 beta
  * C library
  - Further development of disprm and related functions to implement
    the FITS keywords for distortions introduced in WCS Paper IV, thus
    changing disprm's ABI once again.
    disprm's model is now similar to wcsprm's handling of PVi_ma and
    PSi_ma, where the parsed keyrecords are loaded into a set of pvcard
    and pscard structs and wcsset() does the analysis.  For disprm, the
    parsed DPja or DQia keyrecords are loaded into a set of dpkey
    structs for disset() to analyse.
  - New function dpfill() aids in filling a dpkey struct.  Function
    disparms() has been removed.  It was no longer needed as
    disprm::parms[][] is now a "returned" member of the struct.
  - Implementation of the general Polynomial distortion function defined
    in Sect. 3.1 of WCS Paper IV.  The polynomial is defined in terms of
    Paper IV keywords.
  - Bug fixes in diswarp() and linwarp() reported by
    Michael Droettboom.
  - Test program tdis1 now tests a TPV header for closure in two ways:
    directly as a specialist TPV distortion (as before), then by
    translating it into a general polynomial distortion.  It then also
    tests that the TPV and polynomial distortions produce the same
    results.
  * Fortran wrappers
  - Changes to the wrappers reflecting changes to disprm.
  - Bug fixes in fitshdr_f.c, and test programs tdis1.f, tfitshdr.f,
    twcsfix.f, and twcs.f.  All reported and/or fixed by Ole Streicher.
- Update to version 5.1 beta
  * C library
  - Distortions-related bug fixes to linset(), linp2x(), and linx2p().
  - New functions diswarp() and linwarp() compute statistics of the
    distortion functions over a specified domain.  Changed tdis1.c to
    test them.
  - Changes to disprm (so changed ABI).
  * Fortran wrappers
  - Wrappers for diswarp() and linwarp().
- Update to version 5.0 beta
  * C library
  - Implemented the framework of WCS Paper IV (the draft distortions
    proposal) based on a new struct, disprm, and suite of routines with
    header dis.h: disini(), disalloc(), discpy(), disfree(), disprt(),
    disset(), disp2x(), and disx2p().  New test program tdis1.
    Consequent changes to the linprm struct have altered its ABI, thus
    necessitating an increment in the WCSLIB major verion number.
  - wcsset() now recognises the "TPV" projection proposed in an early
    draft of WCS Paper II, and translates it into a disprm distortion -
    by request of Octavi Fors.  Additionally, it recognises "TPU" as
    equivalent to "TPV" but using a prior distortion (coming before the
    linear transformation matrix) rather than sequent (coming after it).
  - In wcspih() and wcsbth(), added relaxation flags to allow PC0i_0ja,
    PV0j_0ma, and PS0j_0ma (i.e. with leading zeroes on the index).
  - Added wcslib_version() to return the WCSLIB version number, as
    suggested by Ole Streicher.
  - Fixed problems uncovered by valgrind in prjbchk() (reported by
    Ger van Diepen), sphx2s(), sphx2s(), spcspxe(), spcxpse(), tabini(),
    and wcshdo_util().
  - Tidied up error reporting, particularly relating to translating
    status returns from lower-level functions.  New functions linperr()
    and celperr() report error messages from the structs they contain
    in addition to their own.
  - Changed output formatting of floating point values in linprt(),
    celprt(), prjprt(), spcprt(), tabprt(), and wcsprt().  Updated the
    test output reference files for tbth1, tpih1, twcsfix, twcssub, and
    twcstab to suit.
  - Tidied up several of the test programs, mostly to free memory
    explicitly before exit so that valgrind doesn't report (non-)leaks.
  * Fortran wrappers
  - Wrappers for the new distortion functions.  New test programs
    tdis1.f and tdis2.f.
  - Updates following changes to wcspih() and wcsbth().
  - Added wrappers for linperr() and celperr().  Also added prjperr_(),
    spcperr_(), and tabperr_() as convenient wrappers on wcserr_prt().
  - Wrapper for wcslib_version().
  * Utilities
  - Added a "lint" function to wcsware to check a FITS header for
    conformance to the WCS standard.  New test program twcslint.
  * PGSBOX
  - In PGCRLB, fixed an incorrect use of the MOD intrinsic reported by
    'gfortran -std=f95' via Jean-Baptiste Marquette.
- Remove upstream-included build_flags.patch

- Update to version 4.25.1:

    with varying degrees of strictness.  Test program twcscompare.
    Contributed by Michael Droettboom.
  - In wcssub(), fixed a bug uncovered by valgrind arising from
    allocation of insufficient memory for temporaries when a new axis
    is added.  Reported by Michael Droettboom.
  - In wcshdo(), don't write RESTFRQ or RESTWAV if zero.
    Also, to distinguish them from integer keyvalues, floating-
    point values will now always be written with an exponent or

  - Update to version 4.21 (2014/03/24)
  * C library
  - New function prjbchk() performs bounds checking on native spherical
    coordinates.  It is invoked automatically by the deprojection (x2s)
    routines if prjprm::bounds&4 is set.  Documented the new bounds
    checking implemented by prjbchk() in the prologue entry for
    wcsbchk().  Improvements to tprj1 to test the vector API of prjx2s()
    and to deal better with out-of-bounds native coordinates returned by
    it.
  - Bug fixes in the projection routines: in hpxx2s() relating to bounds
    checking, bug introduced at 4.20, reported by Michael Droettboom; in
    parx2s() and molx2s() relating to setting the stat vector; in
    hpxx2s() relating to implementation of the vector API; and in
    xphx2s() relating to setting an out-of-bounds value of phi.
