George --
Why would the request ID numbers change after the invocation to the
back-end MPI_Startall()? The request ID numbers were allocated when
the requests were created, so there's no reason that MPI_Startall()
should change them -- hence, there's no need to re-assign the same
values back to the fortran array after the C call.
Specifically: the requests are not INOUT parameters. Unless I'm
missing something, this commit should be backed out -- the problem
that Tim Campbell is running into must be something else.
Did we get his test program?

New Revision: 13079
Modified:
trunk/ompi/mpi/f77/startall_f.c
Log:
Once we start the C requests we have to put back their f_to_c index
in the fortran array, as we might get new C requests from the startall
function.
