cygwin uses unix conventions for paths, it does not understand C:\\ (you 
can see that when scipy tries to build things, the library dir option 
for the linker is -L\\Blas..., not -LC:\\). You should use unix paths - 
to refer to C:\foo, you may use /cygdrives/c/foo or something like that 
(from a cygwin shell).

Also, you should avoid using upper-case: although NTFS handles uppercase 
filename, other parts of windows do not, and that only complicates the 
matter when using cygwin IMO. If you want to stay as close to unix as 
possible, I advise you to keep everything inside /,

cheers,

David
