Without --enable-simd compilation succeeds - maybe my CPU doesn't support SIMD? My CPU is an AMD Athlon XP (1600+ I think).
this error should be unrelated to the gcc version. gcc can only assign xmm registers, if it is sure, you are on a specific machine ... for that you _have_ to use -march= flags covering your machine. i added an --enable-optimize=athlon-xp feature, that does this for you ... should be in cvs, soon ...
Shouldn't we use a run-time cpu detection instead and switch to the optimized SIMD versions then? just dlload an so. I have a bunch of snippets from the xvid sources. (an optimized assembler routines also :)
