-------------------------+--------------------------------------------------
 If a non-static function is defined in more than one object file, the
 results at run-time are unexpected or unpredictable.  I was under the
 impression that there were compiler options to prevent this.  At least on
 Mac OS, these must not be used, as I just ran into this problem.

 So, either we find out which options are needed and add them, or we could
 provide some additional checks in the build system to help catch this
 error.  For example, Cactus scheduled functions defined with the same name
 should be easy to catch.
