musepack-r475-160000.3.2

- Rework libmpcdec.patch and libmpcdec-extern.patch so that they
  apply with -p1, and use autosetup.
- Add libmpcdec-gcc14.patch: fix the build with gcc 14
  (boo#1221008).

- Use %patch -P N instead of deprecated %patchN.

- Add libmpcdec-fastmath-no-const.patch: remove const declarations
  from some arrays which should not have them (boo#1176374).

- Add libmpcdec-extern.patch: add missing extern declarations
  (boo#1160284).

- Remove degree adverbs from description.

- Add baselibs.conf: libmpcdec6-32bit is a dependency for
  gstreamer-plugins-bad-32bit.

- More spec file cleanup:
  * Use SPDX identifiers for License
  * Correct license for libmpcdec (BSD-3-clause)
  * Use https:// for Source and Url
  * Remove __DATE__/__TIME__ mangling, no longer needed with current GCC
  * Remove BuildRoot

- Conflict with libmpcdec-devel, since both packages provide
  libmpcdec.so.
- Use cmake macros.
- Move source modifications from %prep to %build. Makes 'quilt
  setup' more robust.
- Remove %defattr.. No longer needed.

- Initial rpm release (version r475).
- Added a patch "libmpcdec.patch" in order to fix CMakeLists.txt
  to install a libmpcdec shared library and add a missing
  libmpcdec link to libm.
