Install pnetcdf with int64 and uint64 type

[Wei-Keng Liao]

Those test results shown in config.log can be ignored,
as the configure was trying to find a proper data type
to represent 64-bit integers on your machine.

If configure and make ran fine without errors, then your
PnetCDF build is supporting 64-bit integers.

Hi All,

I'm installing pnetcdf using the following commands:
$PNET=/usr/local/software/netcdf_pnetcdf/pnetcdf
$./configure --prefix=$PNET --enable-fortran --enable-large-file-test
$make -j8
$make install

Followed are part of my "config.log".

Does anyone know how to enable int64 and uint64 when installing pnetcdf?
Thank you very much!
