* The MAYBE_VMS_FUNCTION_PROLOGUE macro works for both gcc and g++. It
* first checks to see if the current routine is "main", which will only
* happen for GCC, and add the jsb if it is. If is not the case then try and
* see if __MAIN_NAME is part of current_function_name, which will only happen
* if we are running g++, and add the jsb if it is. In gcc there should never
* be a space in the function name, and in g++ there is always a "(" in the
* function name, thus there should never be any confusion.
