I was unable to reproduce the problem you report, using gcc 2.4.5 on a SunOS
4.1.3 platform.  The warnings you got from gcc may be due to a different
version of gcc, or possibly a different set of patches to SunOS 4.1.3.  In
any case, the warnings you saw about a redefinition of `NULL' redefined are
not serious and can be ignored.

The problem you report with creating the Fortran interface is harder to
explain:

It appears that something killed the fortc process that generated jackets.c
or truncated jackets.c, since your jackets.c is identical to the one
generated here up to the last character in your jackets.c.

Here's the output I got from typing "make all" after setting up configure
the same way you did:

    % make all

    making `all' in directory 
/a/zero/home/russ/build/sparc-4-gcc/netcdf-2.3.2/port

    gcc -traditional -O -c -I.  -Dconst= -DNO_STRERROR -O uddummy.c

    a - uddummy.o

 ...

and so on, with the make completing successfully with no errors.  I don't
know why jackets.c was truncated on your system.  It takes a long time for
fortc to creates jackets.c from jackets.src.  Is it possible some other user
on your system noticed it was taking a lot of resources and killed the
process before it finished?  You might try again with

   make clean all

to see if jackets.c still gets truncated in the same place.
