[MPICH] minor problem with mpif.h with gfortran-4.0 gcc-4.0

[Kamaraju Kusumanchi]

May be this is just me doing something stupid and I hope others will
correct me if that is the case. I compiled mpich2 1.0.2 using gcc-4.0,
gfortran-4.0 on Debian Sid using the --enable-f90 option.

The compilation went fine. But when I tried to run a hello world
program, I got the following errors.

$mpif90 hello_world2.f90

I realized that this is due to the Fortran77 style commenting in
mpif.h file. When I applied the following patch

$diff mpif.h mpif.h.original
1,8c1,8
< !      /* -*- Mode: Fortran; -*- */

Then everything went fine. Is this a bug? If so, could it be fixed in
the future versions?
