Subject: libmpeg2-altivec patch by Magnus Damm <damm@opensource.se>:   Updated
 to version 1.12 from sourceforge   The old version crashed my gcc-3.2.2
 (after allocating 1 Gig memory)   because of unfriendly altivec code, the new
 file is better.   The new file ditches the old assembly version   and it must
 be built with correct altivec-flags
