Summary: cygwin build problems

Initial Comment:
thought I'd try PyOpenGL2 on win2k/cygwin

using cygwin 1.3.5 and the cygwin port of python 2.1.1
and a fresh CVS checkout of PyOpenGL2

first copied config/win32.cfg to config/cygwin.cfg,
since OpenGL progs compiled with cygwin's gcc use the
normal win32 libs (opengl32, glu32, etc.)

here's what the first bit of setup reports:

PyOpenGL 2.0.1.45.a1 setup

System configuration:
    Platform    = cygwin
    GL Platform = WGL
    Numeric     = 20.2.2
    Build Togl  = yes

1. first prob was that I didn't have SWIG, so I got:

swig -version
unable to execute swig: No such file or directory
swig1.3 -version
unable to execute swig1.3: No such file or directory
warning: build_w: Can't find SWIG, will just have to 
do with the existing wrapper source.

which would likely be ok except that soon after:

cc -I/usr/include/python2.1/Numeric -c _configtest.c -
o _configtest.o
unable to execute cc: No such file or directory

I didn't know how to force setup to use gcc rather than
cc, so I took the easy way out and copied
/usr/bin/gcc.exe to /usr/bin/cc.exe

that at least allowed things to progress...

2. next, saw lots of warnings about missing __init.py__
files, most in the Demo subdir

3. finally, failed with:

ugh - sorry about the formatting of the report - hope it
is understandable - if not let me know and I'll upload files
with the requisite info...
