[vtkusers] build errors: Cygwin, python, windows 7

[caleb at howlor.com]

Hi!  I've been using vtk under linix for a while, with great success.  Now
I have need to run at work, on a 64 bit windows 7 machine in a cygwin
environment.  I am attempting to compile with the python wrapping turned
on, and it works through the build to 31% complete, and then...

----------------

I am unsure what else I should provide to inform any advice I might hope to
receive here.


I am more familiar with developing for UNIX, IRIX, Linux, etc.  I am in
murky waters and will gratefully receive any pointers.  Please assume
nothing about my familiarity with a windows environment.

Thanks!
