...I believe I have the answer. Use the microsoft C compiler on your system to 
build netCDF, not the gcc which cygwin is finding for you.

This will generate object files with the .obj extension, and not with the .o
extension.

The MS C compiler is called "cl.exe".

You also need to have your env vars set properly in Cygwin to call the MS C
compiler and have it work. I am not sure what those settings are. If you figure
them out, please let me know.

As you may know, there is a limited number of full-time engineers working on
NetCDF - just me! So we rely on users to help port netCDF to new and
interesting platforms, like cygwin with a commercial windows fortran compiler!

In fact, I am struggling right now to set this up in my automatic testing
environment. The hard part is getting all the env vars correct!

Thanks,

Ed
