This comes from __GNUC_PREREQ in 
mpeglib/lib/util/render/dither2YUV/rgb2yuvdefs.h (line 23 and below). It's 
defined in /usr/include/sys/cdefs.h
The simplest fix should be to
#include <sys/types.h>
into this file (or into everything that #include's it) but I'm lazy :-). So I 
simply leave only 
# define __attribute_used__ __attribute__ ((__used__))
definition (FreeBSD-CURRENT, gcc-3.4.2 here; probably the same will work for 
your version of gcc).
Anybody more knowledgeable: Please commit correct fix, it shouldn't be hard.

Regards,
Vladimir
