[MPICH] MPI_GET_ADDRESS

[Kenneth Rempe]

Bill,

Okay, what am I looking for in the configure output. Is there a why to 
override what configure is setting?
Also, is this a problem because in C++ you can use an unsigned int for 
addresses up to 4GB but in fortran it is a signed integer
which only can go up to 2GB?

Thanks

Ken
