---------------------------------+--------------------------------------
 The assembly support macros defined in the libavutil/mem.h public header
 does not have any prefixes which may cause namespace collisions when
 included by users.

 They should either have some appropriate prefix added, or alternatively
 moved to some internal header since having them public seems to be of
 questionable usefulness.

 This may apply to more defines in other headers as well which perhaps
 might be worth investigating, but DECLARE_ALIGNED happens to actually
 cause a name collision when libavformat/avformat.h is included by x264.
