[SciPy-user] build problem using cygwin

[Geza Groma]

I tried to build scipy from the latest (MAy 13) CVS on a WindowsNT using
cygwin-1.3.10-1 and gcc-2.95.3-5.
It succesfully built atlas.3.3.15 and created the complete liblapack.a
library from LAPACK 3.0. Building of scipy, however,  is stopped at the
creation of the first dll with the error message below.

Any idea what is wrong?
