[FFmpeg-devel] Licensing issue with idct_mmx.c

The file idct_mmx.c (libavcodec/x86/idct_mmx.c) has a GPL license which conflicts with the rest of the libavcodec files.
This file is apparently not used anywhere.

Is this file really needed (mmx is an old architecture)? Would it be possible to change the license to LGPL or move it outside of libavcodec?
The presence of the GPL license forces the client of the libavcodec to manually remove the file, instead of using libavcodec as is.
