The root directory of your regular Windows Python (not Cygwin)
installation; should contain a Lib/ subdirectory. I guess this is my
mistake -- I never set this up to work with Cygwin but no ordinary Python.

However, if you haven't installed that, you can get around the "no python
installation" message by setting PYTHON_STDLIB_PATH to point at your Cygwin
python's Lib/ directory.

In theory, you should be able to set PYTHON_ROOT to c:/cygwin/usr, but I
don't think it actually will make a difference if you set
PYTHON_STDLIB_PATH.

>   PYTHON_VERSION                              (2.2)

Should be 2.2

>   CYGWIN_ROOT                                 (C:\cygwin)

OK

>   GCC_PYTHON_ROOT   $(CYGWIN_ROOT)/usr/local
(C:\cygwin\usr\include\python2.2)

Should be c:/cygwin/usr

> Since I did not really install python, i.e. Cygwin did this, I do

above

Sorry for any confusion,
