Sure but some important programs using it are written in C++ and use the 
ffmpeg includes via the "extern C" trick.
Never mind, I have modified the file to be sure the macro is always 
defined (compying the stdint code) and do not have to modified a bunch 
of independently generated Makefiles by hand.

At least I have tried to make sure the impact of the modification for 
C++ program linked with libav* has been considered as the problem only 
surfaced due to recent commit
