Fixed bug 4103 - SDL_cpuinfo.h provokes warnings with -Wundef on non-x86 hosts Felix Geyer Forwarding from https://bugs.debian.org/892087 quoting verbatim: The SDL2 header SDL_cpuinfo.h generates gcc warnings if the program using it compiles with the -Wundef warning. (In particular, this means that QEMU builds using it fail on at least sparc hosts, since QEMU dev builds use both -Wundef and -Werror.). /usr/include/SDL2/SDL_cpuinfo.h:63:5: warning: "HAVE_IMMINTRIN_H" is not defined, evaluates to 0 [-Wundef] #if HAVE_IMMINTRIN_H && !defined(SDL_DISABLE_IMMINTRIN_H)
