Apparently (or so I am told), the MSYS_* string is for building things actually for MSYS itself, which is imho a bad default. If I just call sh/bash.exe (like I do in a multitude of my scripts), I wouldn't want that to be the default value, especially since it breaks with compat for all sorts of projects (we're not the only project with that problem) - Hendrik _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
