[DebianGIS] grass and 64bit

["Francesco P. Lovergine" <frankie@debian.org>]

Now that amd64 arch just entered the great main world, I wonder if 
it would be useful/needed(?) in grass enabling the '64bit support'
whose use is not so clear to me... 


(C) COMPILATION NOTES for 64bit platforms

To successfully compile GRASS on 64bit platforms, the required
FFTW2 library has to be compiled with -fPIC flag:

    #applies to FFTW2, not GRASS:
    cd fftw-2.1.5/
    CFLAGS="-fPIC" ./configure
    make
    make install

To fully enable 64bit library usage for GRASS on 64bit platforms,
the following additional parameters are recommended/required:

    ./configure \
       --enable-64bit \
       --with-libs=/usr/lib64 \
       ...
