Using either cvxopt-0.9.p8 (in sage-4.3.3) or cvxopt-1.1.2.p2, which is at
http://boxen.math.washington.edu/home/schilly/sage/spkg/, we get this huge
error very quickly upon trying to build:
{{{

IDEAS:
1. Look for complex.h on this page:
http://www.cygwin.com/ml/cygwin/2006-07/threads.html#00763 That has some
ideas.
2. I think Mike Hansen said that he recently released (then unreleased!?)
numpy-1.4 had a drop-in complex.h?
