I think that's not quite true, e.g. older OpenBSD versions lack the
INFINITY define in math.h (even though it is required by C99 and POSIX
IIRC).
A patch to fix this has been discussed on ffmpeg-devel but not applied.
If you can not update your system to follow C99/POSIX better you can add
#define INFINITY (1.0/0.0)
to the file that fails.
