Ben,

I haven't actually built it yet on windows, but I would assume I would use
a netcdf.dll.  Presumely in the short term this could coexist with other
users of netcdf.dll and in the longer term you might migrate to using
GDAL's netcdf support.  However, it isn't too sophisticated yet, so be a bit
wary.  This was an unfunded development (read: quick hack).

I have no intention of including an internal copy of netcdf lib in the same
way that I did for libungif, libpng, and some of the other "in the source
tree" libraries.  I am sure it could be done that way, but I hate to drag
too much more into the GDAL DLL itself.

I hope that answers your questions.

Best regards,
