Thanks, Larry. I think that's true if you install the 32-bit Snow Leopard
kernel. I'll check what this is actually compiling as if I can figure out how
to do that on OSX.
Cheers.

John,
My recollection using gcc and gfortran on Mac OS X 10.5 (Leopard) is that they
both default to 32-bit. My makefiles define CC (and, sometimes, LD) as "gcc
-m64", plus FC as "gfortran -m64" to get things to work. Note: the -m64 flag
is NOT in defined in the CFLAGS, FCFLAGS and LDFLAGS variables -- since -m64 is
really selecting a different compiler/linker, it should be defined as part of
those variables, regardless of the rest of the options.
For example, here's my (non-HDF) make configure of netCDF using
gcc/g++/gfortran:
cd netcdf-$(VERSION) ; \
./configure >configure.log 2>&1 \
CC="gcc -m64" \
CFLAGS="-g -O2" \
CXX="g++ -m64" \
CXXFLAGS="-g -O2" \
CPPFLAGS="-DNDEBUG -DgFortran" \
FC="gfortran -m64" \
FCFLAGS="-g -O2"
(I haven't tried -O3, which supposedly invokes the gcc vectorizer/sse code
generator.)
