Måns Rullgård	439ccc4e0e	Split libavutil/timer.h per architecture Originally committed as revision 18304 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Stefano Sabatini	987903826b	Globally rename the header inclusion guard names. Consistently apply this rule: the guard name is obtained from the filename by stripping the leading "lib", converting '/' and '.' to '_' and uppercasing the resulting name. Guard names in the root directory have to be prefixed by "FFMPEG_". Originally committed as revision 15120 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
