texinfo-7.1-160000.2.2

- Add texinfo-perl-5.42.patch: Fix syntax to be unambiguous
  if (! $str eq '') is not really clear; is it
    (!$str) eq ''
  or
    !($str eq '')
  Perl 5.42 rightly flagges this syntax with:
    Possible precedence problem between ! and string eq
  Assuming !($str eq '') was meant, we can rewrite this as
  $str ne '', which happens to also be used in multiple places
  already (sometimes just a few lines further down in the same
  files)

- add -std=gnu17 to CFLAGS to fix gcc15 compile time error
  (flag can be dropped w/ release 7.2)

- Update to version 7.1 (18 October 2023)
  * Language
  . new generic definition commands, @defblock, @defline and @deftypeline,
    for definitions without automatic index entries
  . new @linemacro facility eases use of generic definition commands
  . new command @link creates plain links (supported output formats only)
  . @cartouche takes an argument to specify the cartouche title
  . you can use the new commands @nodedescription and @nodedescriptionblock
    to give text to be used in menu descriptions in Info and HTML output
  * texi2any
  . @itemx at the beginning of a @table is now an error, not a warning
  . better validity checking of deeply nested commands
  . check that @set and @clear only appear at the start of a line
  . warn about missing menu entries even if CHECK_NORMAL_MENU_STRUCTURE is
    not set.  you can turn this off by setting CHECK_MISSING_MENU_ENTRY to 0.
  . no longer use --enable-encoding and --disable-encoding to determine
    whether to output encoded characters (instead of entities or commands)
    for HTML, XML, DocBook and LaTeX; instead, use the value of the
    OUTPUT_CHARACTERS customization variable.
  . stricter checks on input encoding, in particular more warnings and
    errors with malformed UTF-8
  . support any input file encoding if support exists in the operating
    system, not just a selected list of encodings
  . resolve an alias referring to another alias at definition time
  . internally, use "source marks" to keep all Texinfo source information that
    is not in the final tree (location of macros, values and included files
    expansion, @if* blocks, DEL comment, and @ protecting end of line on @def*
    lines)
  . HTML output:
    . format @subentry and index entries with @seealso or @seeentry in a more
    similar way to printed output
    . output @shortcontents before @contents by default
    . omit colons after index entries by default.  this can still be
    configured with INDEX_ENTRY_COLON.
    . add @example syntax highlighting as a texi2any extension
    . no more capitalization of @sc argument in HTML Cross-references
    . change @point expansion to U+22C6 in HTML Cross-references
    . if a @node is not associated with a sectioning command but is
    followed by a heading command not usually associated to nodes
    such as @heading and this command appears before other formatted
    content, the heading command is assumed to supply the node heading.
    you can customize this with USE_NEXT_HEADING_FOR_LONE_NODE.
  . Info output:
    . new variable ASCII_DASHES_AND_QUOTES, on by default,
    outputs ASCII characters for literal quote or hyphen characters
    in source, rather than UTF-8.  this makes it easier to search
    Info files.
    . new ASCII_GLYPH variable for using ASCII renditions for glyph
    commands (like @bullet)
    . ASCII_PUNCTUATION still includes the effect of these new variables.
    . new variables AUTO_MENU_DESCRIPTION_ALIGN_COLUMN and AUTO_MENU_MAX_WIDTH
    control the format of descriptions in generated menus
  . XML output:
    . place menu leading text and menu separators in elements instead
    of attributes
  * texi2dvi
  . macro expansion with texi2any requires at least version 5.0 (only
    happens with --expand option or with very old texinfo.tex)
  * texinfo.tex
  . in @code, ` and ' output by default with backtick and undirected
    single quote glyphs in the typewriter font.  you can still configure
    this using the @codequoteundirected/@codequotebacktick commands.
  . do not insert a space for @ def line continuation, matching the behavior
    of texi2any
  . align section titles in table of contents when more than 10 sections
  . microtype is off by default, for speed
  . page headings generation is no longer linked to the @titlepage command
  * info
  . when going Up, position cursor on menu entry for current node
  . allow mouse scrolling support regardless of termcap entries.  this
    supports some more xterm configurations.
  . do not use "/index" as a possible file extension for Info files
  * texi2any
    . fix performance regression when Perl binary extension (XS) modules
    are not being used (e.g. with TEXINFO_XS=omit)
  * info
    . further fix of recoding of UTF-8 files to ASCII to avoid text
    disappearing from nodes
    . avoid possible freeze at start of a file with `-v nodeline=pointers'
  * texi2any
    . do not distribute architecture-dependent files
    . build fixed on OpenIndiana 11
  * info
    . further fix of recoding of UTF-8 files to ASCII
    . fix check for presence of man pages on Solaris
  * install-info
    . fix build by avoiding function name clash on some platforms
    . compiler warning re strncat silenced
  * texi2any
    . avoid crashes on empty @image argument and other potential crashes
    (with "Can't use an undefined value as an ARRAY reference" message)
    . avoid hang on @ref command inside section command
  * info
    . fix recoding of UTF-8 files to ASCII when run in C locale
  * js
    . index search fixed for new HTML output
    . some obsolete files removed from distribution
