I've just tried building on a SunOS 4.1.4 with exactly the environment
variables you have specified, except we only have a later version of the
compilers, so I set

     LIBS='-L/usr/lang/SC3.0.1/lib -lansi'

Also, our version of gcc is 2.7.2.  With this, I was able to duplicate
the problem.  ncgen appears to be getting huge values for the small
dimensions in the test file, and the problem can be demonstrated with a
tiny CDL file with only one dimension and one variable.

I'll be trying to isolate it and provide a fix.

You are the first to report this.  Thanks for being persistent!
