Norman,

I have added pymod/cygMakefile to CVS though it isn't likely to be maintained
properly. I have also modified configure to set the EXE macro in
GDALmake.opt.in as well as overriding SO_EXT to dll (not that this is set
by the LD_SHARED macro in aclocal.m4). I also modified the apps/GNUmakefile
to use $(EXE) to properly name .exe executables (though I haven't found this
to be necessary since I added the .exe hack to install-sh).

What I can't seem to do with cygwin-1.3.3 (2001-09-12) is to produce shared
libraries or dlls. How do you do this? What version of Cygwin do I need?

Best regards,
