Hi Doug,

I've reproduced the problem you reported with ncgen in 4.1.1 and
4.1.2-beta2.  It appears that the problem was fixed (by Dennis
Heimbigner) in the current snapshot, which works fine with the
Solar.cdl you attached.  So you should be able to verify the fix in
the current daily snapshot:

  ftp://ftp.unidata.ucar.edu/pub/netcdf/snapshot/netcdf-4-daily.tar.gz

or wait until 4.1.2-beta3 is released (planned for later this weak if
no untacipated difficulties are encountered) or 4.1.2 is released
(planned for a week after 4.1.2-beta3 if no one encounters
unanticipated problems with that release).

Thanks for reporting the problem!
