The limitation is probably one of memory needed to run ncgen.  We have found
that in order to build the netCDF package on MSDOS one has to boot the
machine with a very "bland" environment.  What I mean by this is that
you should try to maximize the amount of program space available by 
not running any TSR (Terminate and Stay Resident) routines.

I will pass this along to the developers.
