[FFmpeg-devel] [patch] Fix compilation error for C++ users

Hm, what is the explanation for this? Can you perhaps link me to relevant
discussion? From the relevant manual page (
http://linux.die.net/man/3/uint64_c), it seems that one does need to define
this macro before including stdint.h; in order to get the right macro
definitions in C++ code.

Also, I just realised I made a big mistake in the patch - it should be
__STDC_CONSTANT_MACROS, not __STDC_LIMIT_MACROS. My apologies, I was kinda
low on coffee. Attached is a fixed version of the patch.

Kind regards,
