Whoops! We forgot to instantiate these -- thanks for catching that.
I have just committed fixes to both the trunk and the v1.0 branch.
This also prompted the addition of the following text in the README
file:
-----
- Open MPI will build bindings suitable for all common forms of
Fortran 77 compiler symbol mangling on platforms that support it
(e.g., Linux). On platforms that do not support weak symbols (e.g.,
OS X), Open MPI will build Fortran 77 bindings just for the compiler
that Open MPI was configured with.
Hence, on platforms that support it, if you configure Open MPI with
a Fortran 77 compiler that uses one symbol mangling scheme, you can
successfully compile and link MPI Fortran 77 applications with a
Fortran 77 compiler that uses a different symbol mangling scheme.
NOTE: For platforms that support the multi-Fortran-compiler bindings
(i.e., weak symbols are supported), due to limitations in the MPI
standard and in Fortran compilers, it is not possible to hide these
differences in all cases. Specifically, the following two cases may
not be portable between different Fortran compilers:
1. The C constants MPI_F_STATUS_IGNORE and MPI_F_STATUSES_IGNORE
will only compare properly to Fortran applications that were
created with Fortran compilers that that use the same
name-mangling scheme as the Fortran compiler that Open MPI was
configured with.
2. Fortran compilers may have different values for the logical
.TRUE. constant. As such, any MPI function that uses the fortran
LOGICAL type may only get .TRUE. values back that correspond to
the the .TRUE. value of the Fortran compiler that Open MPI was
configured with.
You can use the ompi_info command to see the Fortran compiler that
Open MPI was configured with.

Hi
Linking the following program with mpicc from openmpi-1.0 compiled
