Using the OPEN_MPI #define is probably the safest bet to identify the

against Open MPI (because we can/have changed the flags behind the
scenes).
I think one of the possible solutions would be, in the next MPI
standard (will it come very soon?, or not?),
I would like to hope that MPI 2.1 comes out someday in the not-
distant future, but I'm guessing that it'll take quite a while.
specify the library (libraries) for mixed language linking.
MPI has traditionally shied away from specifying this kind of thing,
instead leaving it to be an implementation-specific detail.
What, exactly, do you need to do? Do you need to link an application
that uses all 4 of the MPI language bindings?
