What should have been invoked is:

  f77 -o ftest ftest.o -L../libsrc -lnetcdf -lnsl

where the "-lnsl" is necessary to get the xdr library functions.  This
should have set in the Makefile by the configure script, but it wasn't
because of the problem described below.

OK, we also have a SunOS 5.5 system, but the problem doesn't occur on
ours.  I think the difference is you have /usr/ucb/ in your PATH
environment variable ahead of the /opt/SUNWspro/SC4.0/bin directory, so
you are getting some old /usr/ucb/cc non-ANSI C compiler and libraries
(or make or f77 or ...?)  instead of the Sun ANSI C compiler and
libraries:

> pg4/bin:/usr/include:/export/gzip

Try moving /usr/ucb to the end of your PATH environment variable instead
of near the beginning.  Then run "make clean", delete the file
"config.cache", and try making netCDF again, starting with running the
"configure" script.

I think this indicates the problem.  On our Solaris system, we get:

  checking for xdr_long in default library... no
  checking for xdr_long in -lrpc... no
  checking for xdr_long in -lnsl... yes
  checking XDR implementation... ok
  ...

Please let me know if changing the position of /usr/ucb in your PATH
doesn't fix the problem.
