Ozkan Sezer	86191351c0	acinclude & sdl2.m4 updates: ... - acinclude/alsa.m4, esd.m4: Ran through autoupdate to replace several AC_TRY_[COMPILE|LINK|RUN] with corresponding AC_???_IFELSE , so that autoconf-2.70 doesn't warn. - sdl2.m4: Ditto. - test/acinclude.m4 (sdl2): Ditto.	2020-12-22 17:00:28 +03:00
Ozkan Sezer	44d4a61d92	minor cleanups to configure.ac to reduce autoconf-2.70 warnings a bit. ... configure output is practically unchanged. there are still lots of AC_TRY_COMPILE/AC_TRY_LINK replacements needed to really eliminate the warnings, but that's for another time.	2020-12-14 08:11:40 +03:00
Philipp Wiesemann	0e45984fa0	Fixed crash if initialization of EGL failed but was tried again later. ... The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly uninitialized data structure if loading the library first failed. A later try to use EGL then skipped initialization and assumed it was previously successful because the data structure now already existed. This led to at least one crash in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was dereferenced to make a call to eglBindAPI().	2015-06-21 17:33:46 +02:00
