Hi Marco,

I think there might (?) be a problem with this version of this
package, or specifically the liblapack0-devel (since it includes
liblapack.dll.a import library).

The import library references "cyglapack.dll" as the DLL name.
However, it actually should be "cyglapack-0.dll".  So software (such
as Numpy) that linked with lapack using the import library is broken.

Thanks,
Erik
