Excellent -- thanks!

A good plan. We made the decision that the C++ compiler *must* support
bool for LAM/MPI; it dramatically simplifies the back-end code (rather
than try to do clever things with #define, etc.). Compilers that don't
support bool technically don't support the MPI C++ bindings, anyway
(because "bool" is in some of the official bindings). This is probably
arguable either way, but we've chosen to interpret the standard this way.
:-)
Regardless, the C++ bindings are a very thin (and usually inlined) layer
on top of the C bindings, so even if you use g++, your performance should
be fine.

Excellent catch; we don't have access to AIX 4.3.3 anymore to test on.
I'll fix this so that 7.0final should compile fine on AIX.
FYI: 7.0 is currently being held up by some minor buglets in the Myrinet
code which we hope to have solved "real soon now".
