You know this all looks very similar to the reason why rolfv putback
r20351 which essentially defined out restrict within
opal_config_bottom.h when using Sun Studio.

The AC_C_RESTRICT test only checks the C compiler, yet. It's an
Autoconf-builtin test; we didn't write it.

Odd that you get "restrict" and I get "__restrict". Hrm.

Well, I suppose that one solution might be to disable those prototypes
in the op.h header file when they're included in (that's
a source file in the ompi_info executable; it shouldn't need the
specific MPI_Op callback prototypes). Fortunately, we have very little
C++ code in OMPI, so this isn't a huge issue (C++ is only used for the
MPI C++ bindings -- of course -- and in some of the command line

Let me see what I can cook up, and then let me see if I can convince
George that it's the correct answer. ;-)
