Path MPICH-V for MPICH the MPI Implementation

        UXPM      (UXP/M. Untested.)
        uxpv      (uxp/v. Untested.)

    Others may be recognized.

Special notes:

For SGI (--with-arch=IRIX) multiprocessors running the ch_p4 device, use
-comm=ch_p4 to disable the use of the shared-memory p4 communication
device, and -comm=shared to enable the shared-memory p4 communication
device.  The default is to enable the shared-memory communication device.

# Special environment variables
# MPICH_WARNING_SEP - if set, is echoed around warning messages.  This is
# used to simplify automated testing where we want to ignore warning messages
# Specifically, echo '>'$MPICH_WARNING_SEP preceeds the warning and
#               echo '<'$MPICH_WARNING_SEP follows it
# finderrors and findnosuccess use the same environment variable to 
# skip output
