-/* 'objc_exception_throw' throws the exception 'exception', which is
-   an exception object.
-
-   Calls to 'objc_exception_throw' are automatically generated by the
-   compiler: an Objective-C "@throw exception;" statement gets
-   compiled into the equivalent of "objc_exception_throw
-   (exception);".
-
-   'objc_exception_throw' searches for a @catch() that can catch the
-   exception.  By default, @catch (MyClass object) will catch all
-   exception objects that are of class MyClass or of a subclass of
-   MyClass; if the exception object is 'nil', then the exception can
-   only be caught with a catch-all exception handler where no
-   exception class is specified (such as @catch(id object)).  This
-   behaviour can be customized by setting an 'objc_exception_matcher'
-   function (using objc_set_exception_matcher(), see below); if one is
-   set, it is used instead of the default one.
-
-   If the exception is uncaught (there is no @catch() to catch it),
-   the program aborts.  It is possible to customize this behaviour by
-   setting an 'objc_uncaught_exception_handler' function (using
-   objc_set_uncaught_exception_handler(), see below); if one is set,
-   it is executed before abort() is called.  An uncaught exception
-   handler is expected to never return.  */

-
-/* The following functions allow customizing to a certain extent the
-   exception handling.  They are not thread safe and should be called
-   during the program initialization before threads are started.  They
-   are mostly reserved for "Foundation" libraries; in the case of
-   GNUstep, GNUstep Base may be using these functions to improve the
-   standard exception handling.  You probably shouldn't use these
-   functions unless you are writing your own Foundation library.  */

-   by the @catch clause (for example, in "@catch (Object *o)", the
-   catch_class is Object).  It should return 1 if the exception should
-   be caught by a @catch with a catch_class argument, and 0 if
