When you rebuilt ncgen after modifying ncgen.y, I suspect that yacc was
never invoked to generate a new version of ncgentab.c from ncgen.y.
This may be because of an error in the ncgen Makefile.  Please replace
the ncgen Makefile with the one I've appended.  (Please try to
preserve the "TAB" characters in the Makefile, which may be lost if you
just cut-and-paste it.  It would be better to save this message in a
file, then delete everything that's not the Makefile.)

Next, in the ncgen directory, delete ncgentab.c and ncgentab.h, make
sure the ncgen.y is the patched version, and try "make all" again in the
ncgen directory.

If this succeeds in building a new ncgen, you can test it on the
following 5-line file, which you should store in fbug.cdl (in this case
you can just cut-and-paste, tabs are not important).

- -----------------------cut here for ncgen/fbug.cdl---------------------
netcdf fbug {
variables:
        float ff;
            :_FillValue = -9999.99f;
}
- -----------------------------------------------------------------------

Then, test if the ncgen is fixed by invoking

  ./ncgen -b fbug.cdl

This should create a netCDF file fbug.nc and produce no error messages,
if the error is fixed.  I've just verified all of this on my Sun, but if
you have any problems, please let me know.  Thanks!

Thanks, and sorry this is so complicated to test.
