Sorry, we don't run Windows XP here and don't have the Absoft
compilers you are using, so we can't duplicate the problem.  I'm
CC:ing another developer, John Caron, who runs Windows and provided
the Windows support we make available, in case he can help.

That sounds like good advice.  And since you are using different
compilers than we are, you should generate the library with your
compilers.

If you got the netcdfs.lib static library from us, then that would
have been generated with the Microsoft compiler.

You would have that information.  Maybe you could put together a small
example that fails and send that to the Absoft folks.

Sorry, but I don't think so.  We make all our sources and tests
available, so they should be able use their compiler on our sources,
run the tests we provide, and debug the problem.
