With python 2.5, you can build extensions with MinGW. I haven't tried to 
build numpy though.

CygWin is NOT the same as MinGW. They both are gcc, but IIUC, cygwin 
builds against the cygwin unix-like standard libs, and MinGW builds 
against the system libs -- so only MinGW can link with a Python build 
with MSVC.

I can't help you with MinGW and either g77 or BLAS/LAPACK though.
