I send you a mail with flags needed for SSE.
It seems running with Emmerald.
One small problem:
no "cp" and no "rm", for makefiles. (What should I download?)
On the other side, I use the binary port of Atlas, which was also
compiled with SSE(but no L1,L2) reaching 200MFlops.
The fact that Atlas works, I may think MinGW was working correctly.
I am trying to verify that I reach 900MFlops with Emmerald now.

If the package you're trying to build is designed to be
installed with commands like './configure && make' then
you should definitely build it in the MSYS environment.
Otherwise...cp and rm are part of gnu fileutils. In the
past I've extracted prebuilt win32 binaries from
(copied from old documentation--not tested recently)
and that's probably still the fastest way to work around
your immediate difficulty.
But these days I'd download the source code from gnu.org
and build it with MSYS (from mingw.org).
Of course, if you have MSYS, it already includes versions
of these and other common utilities. I'm not sure whether
they've been customized to work only in the MSYS environment.
