[mpich-discuss] Excluding c++ compiler from configure script

[Jeff Hammond]

Hi Pavan,

I filed a bug on this 9 months ago but was told that the problem was
unavoidable and that it would not be fixed.  The solution I proposed
to the user was in fact the one suggested by Dave in response to that
ticket (except /bin/false -> /bin/true, because it doesn't matter).

See https://trac.mcs.anl.gov/projects/mpich2/ticket/1570 for details.

Best,

Jeff
