I think you need first to read up on MSYS, which can provide what you need 
in a simpler way than Cygwin. The MS-Windows native binary is actually an 
MSYS build - MSYS provides enough shell-level support to run configure 
scripts. If Windows Perl and gnuplot are available in your path, they 
should also integrate well enough. There are issues with the ordering of 
directories in the path, which is not always simple, but may be less of a 
problem than using Cygwin.

A concern that I have had is that the current installation is rather 
invasive - I already have MinGW and MSYS (and tcltk), and build proj4 and 
GDAL there anyway, but the install procedure seems to assume a "bare" 
platform - is it possible to respect the fact that some software may 
already be present? By the way, I think PostgreSQL is absolute overkill 
for Windows.
