[SciPy-dev] Strange error on cygwin - building cluster

I've hit a problem building Scipy on an Athlon system with W2K and
Python 2.3.4, using Cygwin.  It's quite similar to one that Travis O.
posted to this list a while back

This the the command that's failing:

g++ -O2 -Wall -Wstrict-prototypes -DNUMERIC_VERSION="\"23.6\""
-DNO_ATLAS_INFO=2 -IC:\Python23\include -Ibuild\src
-IC:\Python23\include -IC:\Python23\PC -c Lib\cluster\src/vq_wrap.cpp -o

... And as I look at that, I'm wondering why it says NO_ATLAS_INFO -- I 
did build Atlas and have the environment variable set.  It also seems to 
be ignoring my FFTW environment variable.  Grr.

Here's the output for the command above:

I don't *need* cluster, though I'm sure I'll want it at some point.  In
addition to not being able to figure out the fix for this, I'm wondering
how I can simply skip this module for now.

I'll be happy to post more info if that'll help.
