Hi Akshar
Maybe the F90FLAGS="-ff2c" flag is causing the problem?
What if you remove it and use gfortran for F77 and FC?
Also, my 'configure -help' (a bit old, MPICH2 1.3.2p1)
mentions FC, not F90, as the environment variable to be set.
For what it is worth, MPICH2 builds fine for us, with
gcc, g++ and gfortran (for F77 and FC).
My two cents,
Gus Correa
