Unable to use MPICH2 during Petsc compilation

[Satish Balay]

You can't build PETSc libraries with mpich1 and expect it to work with
mpich2.

If there was a configure failure with mpich2 - then send us the
relavent configure.log file. Configure should have found mpich2 - if
it were installed in the default location. Perhaps there was some
other issue here..

Also - if mpich1 works - I'll recommend sticking with it on
windows. [unless there is a specific reason - requiring mpich2]
