openmpi/ompi/mpi/f77/reduce_f.c
Rainer Keller 9b91ac2fa3 Thanks to Daniel Spangberg for noticing this problem in the f77
interface:
 - Fix the handling of MPI_BOTTOM in various places
   Update of r15030
 - While being at it, handle MPI_IN_PLACE in the same way.
   Convert OMPI_ADDR -> OMPI_F2C_BOTTOM
   Convert OMPI_IN_PLACE -> OMPI_F2C_IN_PLACE
   and have them converted before the actual call.
 - Approved by George and tested with icc and simple f77 mpi-program and
   with program by Daniel.

This commit was SVN r15129.
