Seems like what is happening here is that the test is trying an open of
a file that is not a netcdf file, and getting an error code of 2 instead
of the expected error code of -51 (NC_ENOTNC - not a netcdf file).

Does the file that is being opened exist?

Not sure what GMT is...

Probably due to a fix in the code somewhere.

Well it can be investigated by firing up the debugger and seeing what is
happening!

Windows is actually supported for the C library, though not visual
studio. For (ming32w generated) windows DLLs, get this file:
ftp://ftp.unidata.ucar.edu/pub/netcdf/snapshot/netcdf4_dlls_vs.zip

Sorry, opendap is not yet supported for DLL builds.

Thanks,
