  * In the general case, there are three steps toward handling SIGFPE in any
  * Python code:
- * 
+ *
  * 1) Add the *_PROTECT macros to your C code as required to protect
  *    dangerous floating point sections.
- * 
+ *
  * 2) Turn on the inclusion of the code by adding the ``--with-fpectl''
  *    flag at the time you run configure.  If the fpectl or other modules
  *    which use the *_PROTECT macros are to be dynamically loaded, be
  *    sure they are compiled with WANT_SIGFPE_HANDLER defined.
- * 
+ *
  * 3) When python is built and running, import fpectl, and execute
  *    fpectl.turnon_sigfpe(). This sets up the signal handler and enables
  *    generation of SIGFPE whenever an exception occurs. From this point
  *    on, any properly trapped SIGFPE should result in the Python
  *    FloatingPointError exception.

  * Step 1 has been done already for the Python kernel code, and should be
  * done soon for the NumPy array package.  Step 2 is usually done once at
  * python install time. Python's behavior with respect to SIGFPE is not
  * changed unless you also do step 3. Thus you can control this new
