[netCDF #CTW-339617]: netcdf version check

Hi John,

Sorry to have been unresponsive, we've been doing final testing before a
release.

I believe that would be a harmless no-op.  I don't have any platforms here to
test
on that don't support LFS, so I can't just run a test easily.  But the above
should
work fine even on platforms that don't support LFS.  A "file too large" error
would
occur in case this program later tried to write a file > 2 GiB in size. but
things
would work fine up to that poiunt, and the file created would have 64-bit
offsets.
