3// Note: FFmpeg's AVERROR and AVUNERROR are conditionally defined based on
4// whether EDOM is positive, claiming that "Some platforms have E* and errno
5// already negated". This can be traced to a commit in 2007 where "some
6// platforms" were specifically identified as BeOS (so maybe also Haiku?):
7// https://github.com/FFmpeg/FFmpeg/commit/8fa36ae09dddb1b639b4df5d505c0dbcf4e916e4
8// constness is more valuable than BeOS support, so if someone really needs it,
9// send a patch with cfg_attr.
