There is no actual code for these defines. I never really understood how
they work but setting them gives you code that supports 64 bit files on 32
bit machines so it must enable so predefined code in some kind of system
library somewhere. Hence there is no #ifdef inside the AMBER code
corresponding to these. As far as I know it is benign to always include
these, even on 64 bit OSes so we should probably just include it for all

The configure update looks good to me. Although we should probably include
this for Fortran code as well so sander gets compiled with it as well. I'm
not sure if it is doing that right now.

All the best
