 *
 *
 * 4) Specials for libschily
 *
 * define HAVE_SCANSTACK Scanning of the stack is implemented for this
 *			architecture:
 *				getfp()
 *			and the derived functions:
 *				handlecond(), raisecond()
 *			are working.
 *
 * XXX It is most likely that getfp() does not really work correctly
 * XXX if getav0() is not working.
 * XXX For this reason, HAVE_GETAV0 is not used anymore.
 * XXX Instead avoffset.h is included and the existence of
 * XXX AV_OFFSET and FP_INDIR is checked instead.
 *
 * define HAVE_GETAV0	Scanning of stack and locating the arg vector
 *			is implemented for this architecture:
 *				getav0()
 *			is working.
 *			get_progname() in saveargs.c will work in the main
 *			thread without a prior call to save_args().
