Would that be *any* IBM/AIX system or only certain ones?  What compiler
would be used?  What does the "-q64" option do?

Russ is in Australia this week and should return next Tuesday.

I'm afraid I don't know anything about the "q64" problem and I don't
have an account on Blackforest.  We do, however, have an IBM/AIX system
here:

    AIX gale 3 4 001330614C00

Could I investigate your problem on this system?  NB: The "man cc" page
on this system doesn't show a "-q64" option.

As far as I know, our intention is to support the netCDF library as
much as possible consonant with the netCDF data model and our limited
resources.  The current netCDF package is already compliant with the
64-bit mode of an Alpha/OSF1 system.
