*********************************************
* Overview of the system for handling SIGFPE:
*
*
* This file (Include/pyfpe.h) defines a couple of "wrapper" macros for
* insertion into your Python C code of choice. Their proper use is
* discussed below. The file Python/pyfpe.c defines a pair of global

* named fpectl. This module is standard in every respect. It can be loaded
* either statically or dynamically as you choose, and like any other
* Python module, has no effect until you import it.
*
*
* 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
* facility at compile time, or run time, or both.

* If a floating point error occurs in dangerous_op, foobar returns 0 (NULL),
* after setting the associated value of the FloatingPointError exception to
* "Error in foobar". ``Dangerous_op'' can be a single operation, or a block
* of code, function calls, or any combination, so long as no alternate
* return is possible before the PyFPE_END_PROTECT macro is reached.
*
*
* The macros can only be used in a function context where an error return
* can be recognized as signaling a Python exception. (Generally, most
* functions that return a PyObject * will qualify.)
*
*
* Guido's original design suggestion for PyFPE_START_PROTECT and
* PyFPE_END_PROTECT had them open and close a local block, with a locally
* defined jmp_buf and jmp_buf pointer. This would allow recursive nesting

* variables need to be declared with the "volatile" type qualifier to keep
* setjmp from corrupting their values. Some current implementations seem
* to be more restrictive. For example, the HPUX man page for setjmp says
*
*
* Upon the return from a setjmp() call caused by a longjmp(), the
* values of any non-static local variables belonging to the routine
* from which setjmp() was called are undefined. Code which depends on
* such values is not guaranteed to be portable.
*
*
* I therefore decided on a more limited form of nesting, using a counter
* variable (PyFPE_counter) to keep track of any recursion. If an exception
* occurs in an ``inner'' pair of macros, the return will apparently
* come from the outermost level.
