**=========================================================================

** Build new XML-RPC values from a format string. This code is heavily

** inspired by Py_BuildValue from Python 1.5.2. In particular, our

** particular abuse of the va_list data type is copied from the equivalent
|

** Python code in modsupport.c. Since Python is portable, our code should
