Description
On Cygwin, Sage needs c99 complex support which can be provided by the cephes library from netlib.org / www.moshier.net
There is an spkg at http://sage.math.washington.edu/home/mhansen/cygwin_port/cephes-2.8.spkg
We need to decide the best way to include this since it is only need on Cygwin (and maybe FreeBSD, etc.).

Is it the same Solaris-only cvxopt problem that was solved (for cvxopt) by adding sun_complex.h there? If yes, then it might be good to include Solaris in the list of architectures for which cephes is installed.

Sorry, I spoke too soon -- this doesn't quite fix the problem with cvxopt since it doesn't check $SAGE_LOCAL/include. There is some other cleanup work that needs to be for the cvxopt-1.1.2 spkg as well.
Also, this is a little different than the Solaris issue since Cygwin doesn't have a complex.h, which is what the spkg provides.

I did what Jason Grout suggests above as a little referee patch, and merged this into 4.4.3.alpha0.

How about test the OS name in spkg-install, and if it is cygwin, do something, otherwise return successfully without doing anything?
