Bug 4392

Summary: SDL_cpuinfo.h breaks compilation with C bool type
Product: SDL Reporter: Luke Dashjr <luke-jr+sdlbugs>

Description Luke Dashjr 2018-11-20 03:35:11 UTC 
Bug 3993 was "fixed" by #undef'ing bool. But this breaks C99's stdbool.h bool too.

For example, mpv's build fails with:

../audio/out/ao_sdl.c:35:5: error: unknown type name ‘bool’

It seems ill-advised to be #undef'ing *anything* here - what if the code including SDL_cpuinfo.h actually wants to use altivec?

I also don't understand why altivec.h is included in this header at all. It doesn't seem to use it?

Good points. This is fixed, thanks!
