[SciPy-user] Problems compiling SciPy in Cygwin

I have unsuccessfully been attempting to compile SciPy under Cygwin on a
Windows XP system, with the latest versions of all available programs
installed on Cygwin.

I have tried both SciPy 0.3.2 and the current version from subversion
and encounter similar problems although in different locations.  The
last messages when compiling SciPy 0.3.2 are as follows:

With the version from subversion I get a similar error while building
numpy.core.umath.  I did some testing that seemed to suggest that the
problem is the -O3 in the gcc options, but I was unable to figure out
how to change it.  Any suggestions?
