I notice you say it is a Pentium M, yet ATLAS is compiling things
with the assumption that it is a coreduo:
-DATL_ARCH_CoreDuo -DATL_CPUMHZ=800 -DATL_SSE3 -DATL_SSE2 -DATL_SSE1
-DATL_GAS_x8632
I am guessing the speed is right but the rest is not. Was your successful
build
using these parameters? I had in one instance a non-working ATLAS because
the
cpu type was misdetected (wanted to use sse3 when it didn't have them).
The build
was curiously successful but the library was unusable.
