This test covered __builtin_bswap32 and __builtin_bswap16 separately,
because it was written to support gcc versions that predated the
introduction of __builtin_bswap16. The minimum supported gcc version
now understands both intrinsics, so simplify the test to cover all three
at once.
- Add support for a sequence of guard predicates for a test, rather than
limiting to a single predicate.
- Use that support to skip the dylibbundler test when
user_settings.macos_add_frameworks makes the test unnecessary.
- Use StaticSubprocess to avoid running dylibbundler repeatedly if
building multiple targets for which the test is necessary.
- Capture stderr from the child process, and log it, instead of letting
it be written directly to the stderr inherited from the caller of
SCons.
- On failure, write to the SConf log the return code of dylibbundler,
its stdout, and its stderr. This may help users diagnose the problem
if it is more complicated than the tool not being installed.
- On failure, show a more direct suggestion about how to avoid needing
dylibbundler.
The last PhysFS 1 release was in March 2009. The last PhysFS 2 release
was in August 2017, shortly before the release of PhysFS 3 in September
2017. Most distributions have moved to PhysFS 3. Drop support for
PhysFS 1 and PhysFS 2. PhysFS 2 support could be restored if there is
interest.
Rebirth built with OpenGL has a hard dependency on the GL utility
library, but did not have a configure time test to report this. Add
one.

Add an inclusion of <SDL.h> since, for Windows targets, this triggers a
chain of includes that leads to <intrin.h>, which causes
-Wredundant-decls to print a diagnostic. This allows Windows targets to
declare -Wredundant-decls as unusable, while enabling it for non-Windows
targets.
This adds a new dependency, but most systems likely already have
SDL_image installed. Use of SDL_image can be disabled, but this is
discouraged, because various in-game interfaces assume the use of the
original background.
The old implementation automatically corrected for filename case. The
new implementation expects that the supplied filename can be passed to
PYHSFS_openRead as-is. All known uses in-game have been corrected to
satisfy this requirement. If the new stricter match requirement becomes
a problem, a variant of PHYSFSRWOPS_openRead that adjusts filename case
could be created for use here.
- Update install instructions
- Update ebuild
- Update Arch PKGBUILD
The existing test for gcc pr #82541 was insufficient, and allowed using
-Wduplicated-branches with gcc-7 in some cases it should not. Extend
the test to cover these cases.
mmontag reported that the OS X linker warns when attempting to search a
framework directory that does not exist. Suppress this warning by
checking for the directory and not adding it to the search path if it
does not exist.
