I know what it intends to do:  fpectlmodule.c intends to enable the HW
FPU divide-by-0, overflow, and invalid operation traps; if any of
those traps trigger, raise the C-level SIGFPE signal; and convert
SIGFPE to a Python-level FloatingPointError exception.  The comments
in pyfpe.h explain this best.
