Subject: [PATCH] [project @ 2005-11-08 12:31:36 by simonmar] unless I'm
 mistaken, only x86 needs -ffloat-store.  x86_64 certainly
 doesn't need it, because it uses SSE2 with the
 correct-sized floating point registers and doesn't store
 temporary results with more precision than results in
 memory.
