* The signal handler for SIGFPE is actually declared in an external
* module fpectl, or as preferred by the user. These variable
* definitions are required in order to compile Python without
* getting missing externals, but to actually handle SIGFPE requires
* defining a handler and enabling generation of SIGFPE.
