[Ffmpeg-devel] Problems with preC99 compilers

[Māris Nartišs]

Hi,

I was compiling recent GRASS GIS version but it failed on ffmpeg includes due 
to one line comments. One line comments (//) where introduced in C99, thus 
preC99 compilers do not understand them.

I have 2 questions:
1) Is C99 compiler a must for ffmpeg?
2) Will You change comments in header files to preC99 form? (I mean - do we 
need a special ffmpeg related notice/workaround for preC99 compiler users in 
GRASS or we can wait for new ffmpeg version.)

Tested on GNU/Linux x86
gcc version 4.1.2 20060920 (prerelease)
ffmpeg 3:0.cvs20060823


Please CC me, as I'm not on list.
Thanks for reading,
Maris.
