-/* Call FUNC(UIOUT, FUNC_ARGS) but wrapped within an exception
-   handler.  If an exception (enum return_reason) is thrown using
-   throw_exception() than all cleanups installed since
-   catch_exceptions() was entered are invoked, the (-ve) exception
-   value is then returned by catch_exceptions.  If FUNC() returns
-   normally (with a positive or zero return value) then that value is
-   returned by catch_exceptions().  It is an internal_error() for
-   FUNC() to return a negative value.
-
-   For the period of the FUNC() call: UIOUT is installed as the output
-   builder; ERRSTRING is installed as the error/quit message; and a
-   new cleanup_chain is established.  The old values are restored
-   before catch_exceptions() returns.
-
-   The variant catch_exceptions_with_msg() is the same as
-   catch_exceptions() but adds the ability to return an allocated
-   copy of the gdb error message.  This is used when a silent error is 
-   issued and the caller wants to manually issue the error message.
-
-   MASK specifies what to catch; it is normally set to
-   RETURN_MASK_ALL, if for no other reason than that the code which
-   calls catch_errors might not be set up to deal with a quit which
-   isn't caught.  But if the code can deal with it, it generally
-   should be RETURN_MASK_ERROR, unless for some reason it is more
-   useful to abort only the portion of the operation inside the
-   catch_errors.  Note that quit should return to the command line
-   fairly quickly, even if some further processing is being done.
-
-   FIXME; cagney/2001-08-13: The need to override the global UIOUT
-   builder variable should just go away.
-
-   This function supersedes catch_errors().
-
-   This function uses SETJMP() and LONGJUMP().  */
