[mpich-discuss] Getting MPICH2 to find/use g95 fortran

Thank you very much, Pavan!  I'm not really a command line user - I
assume this will cause MPICH to compile with g95 and also to use g95
when compiling other programs to run under MPI.   I'm not sure of the
syntax of the "&&" command - is that causing it to run make with the
previous line as input?

Thank You Again!!
