Hi Frank

I managed to build this using the CVS Cygwin files using
./configure --without-python --with-grass=no --with-jpeg=internal --with-geo
tiff=internal --with-libtiff=internal

this should probably be mentioned somewhere in a readme
or did I miss something reguired inorder to be able to link successfully
with the Cygwin distributed libraries

Hopefull I will be able to figure out a python Distutils setup.py
to do the Python extension in a cross platform way.

Also I am a bit concerned that there may be problems using gdal
and Cygwin with a GUI because of the following from cpl_port.h

/* ==================================================================== */
/* This will disable most WIN32 stuff in a Cygnus build which */
/* defines unix to 1. */
/* ==================================================================== */
#ifdef unix
# undef WIN32
#endif

I believe the generally accepted way of doing this in the Cygwin community
is to do something more along the lines of

#if (defined(WIN32) || defined(_WIN32)) && !defined(__CYGWIN__)
do things ala WIN32 API
#else
// do things POSIX way
#endif

This allows the use WIN32 or _WIN32 as flags to be used when wanting
to use the Windows GDI and still use the Cygwin POSIX layer.

I am more then willing to do some or all of the 'grunt' work required
if I knew what we wanted.
