[Gm2] cvs latest changes

[gaius]

Hi,

firstly many thanks to all who have been submitting bug reports - I
will work my way through them in due course!  Some minor changes have
been applied to the cvs, in summary:

  *  -fclean is now implemented which removes the objects which -fmakeall
     will build.  -fclean must be used with -fmakeall.
  *  the option -fcheck-all has been renamed -fsoft-check-all.
  *  added documentation explaining the above and also a small section on
     how exception handling is implemented.

hope these are useful.

regards,
Gaius



     * gm2/lang-options.h:  added -fclean as a legal option.
