Hi Frank

Recent versions of ld 'might' link with 'C' dll's but NOT C++ dlls
I will investigate ECW when I get a chance

attached find some cygwin makefile mods
note that I can build a Cygwin pymod extension

I can build a libgdal.dll but I still have to manually
change the SO_EXT = in the GDALmake.opt file

I didn't see where this was being set in the configure.in script

$ python
Python 2.1.1 (#19, Oct 22 2001, 14:56:28)
[GCC 2.95.3-5 (cygwin special)] on cygwin
Type "copyright", "credits" or "license" for more information.
