[netCDF #DAH-931198]: Problem with basic make /check on mac with gnu compilers

Hi Lydia,

Those warnings indicate it is still trying to build the Fortran APIs,
as those all begin with nf_ or nf90_.

I think you are using the gcc that comes with MacOS X, but a gfortran
installed in /usr/local/bin/gfortran that's not compatible with it.
On MacOS X, I've always had to use the same version gcc as gfortran,
and then things seem to work fine.

For example, I built netcdf-4.1.1 on MacOS X 10.6.3 using the gcc and
gfortran versions 4.4.1 from the gcc-leopard-intel-bin.tar.gz (Intel
Mac) link on http://hpc.sourceforge.net/, but you could probably also
use the 4.5 versions, from the gcc-snwleo-intel-bin.tar.gz (Snow
Leopard) link on the same web site.  These are binary distributions, so 
installation is quick and easy installing matching gcc/gfortran in 
/usr/local/bin according to the instructions on that site:

  ... Download my binaries, and cd to the download folder. Then gunzip
  gcc-bin.tar.gz (if your browser didn't do so already) and sudo tar
  -xvf gcc-bin.tar -C /. It installs everything in /usr/local. You
  invoke F95 by typing gfortran. You will also need to have Apple's
  Developer Tools installed. ...

and setting my PATH to include /usr/local/bin fist, so those gcc and
gfortran versions were found by the configure script.  Then everything 
just worked when I invoked

  ./configure --prefix=<whatever>
  make check
  make install

including the Fortran and C++ interfaces.
