see: 0421 15:12 Michael Niederm (3.9K) [FFmpeg-devel] [PATCH] avutil/mem: remove av_realloc / av_malloc incompatibility warning i think thats a better choice than maintaining all memory allocation in 2 incompatible systems [...] -- Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB Many things microsoft did are stupid, but not doing something just because microsoft did it is even more stupid.
