-DESCRIPTION
-<<signal, raise>> provide a simple signal/raise implementation for embedded
-targets.
-
-<<signal>> allows you to request changed treatment for a particular
-signal <[sig]>.  You can use one of the predefined macros <<SIG_DFL>>
-(select system default handling) or <<SIG_IGN>> (ignore this signal)
-as the value of <[func]>; otherwise, <[func]> is a function pointer
-that identifies a subroutine in your program as the handler for this signal.
-
-Some of the execution environment for signal handlers is
-unpredictable; notably, the only library function required to work
-correctly from within a signal handler is @code{signal} itself, and
-only when used to redefine the handler for the current signal value.
-
-Static storage is likewise unreliable for signal handlers, with one
-exception: if you declare a static storage location as `<<volatile
-sig_atomic_t>>', then you may use that location in a signal handler to
-store signal values.
-
-If your signal handler terminates using <<return>> (or implicit
-return), your program's execution continues at the point
-where it was when the signal was raised (whether by your program
-itself, or by an external event).  Signal handlers can also
-use functions such as <<exit>> and <<abort>> to avoid returning.
-
-<<raise>> sends the signal sig to the executing program.  It returns zero if
-successful, non-zero if unsuccessful.
-
-The alternate functions <<_signal_r, _raise_r>> are the reentrant versions.
-The extra argument <[reent]> is a pointer to a reentrancy structure.
-
-
-@c FIXME: do we have setjmp.h and assoc fns?
-
-RETURNS
-If your request for a signal handler cannot be honored, the result is
-<<SIG_ERR>>; a specific error number is also recorded in <<errno>>.
-
-Otherwise, the result is the previous handler (a function pointer or
-one of the predefined macros).
-
-PORTABILITY
-ANSI C requires <<raise>>, <<signal>>.
-
-No supporting OS subroutines are required to link with <<signal>>, but
-it will not have any useful effects, except for software generated signals,
-without an operating system that can actually raise exceptions.

- * signal.c
- * Original Author:	G. Haley
- *
- * signal associates the function pointed to by func with the signal sig. When
- * a signal occurs, the value of func determines the action taken as follows:
- * if func is SIG_DFL, the default handling for that signal will occur; if func
- * is SIG_IGN, the signal will be ignored; otherwise, the default handling for
- * the signal is restored (SIG_DFL), and the function func is called with sig
- * as its argument. Returns the value of func for the previous call to signal
- * for the signal sig, or SIG_ERR if the request fails.
