If __FUNCTION__ is already in use right now (and hence supported by all compilers we have), it should be fine to use it again, so no need for complex ifdefs, I would think. In fact I just checked, and its in use in a key part in avformat, not even an optional module, so any compiler not supporting it would already fail building it now. - Hendrik _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
