But I tried to add the gcc target option of "-m64" to make x86_64 code to
the CFLAGS for the DARCH = X86_64 in the configure file, but the same
errormsg was shown.

Any idea how I can fix this?

Another question not related, but brought up from reading glossy marketing
pamphlets, I belive the Opteron 280 which I have support SSE3, and when
using x264 with older CPU's it takes advantage of MMX,SSE & SSE3 among other
things, does x264 also support SSE3?
