to *not* use the STL as well as removing the STL use from the error handler routines. This was removing the STL from the C++ bindings (Solaris has 2 versions of the STL; if OMPI uses one and an MPI application wants to use another, Bad Things happen). The main idea is to wrap up the C++ callback function pointers and the user's extra_state into our own struct that is passed as the extra_state to the C keyval registration along with the intercept routines in intercepts.cc. When the C++ intercepts are activated, they unwrap the user's callback and extra state and call them. This commit was SVN r17409.
