## Revision 1.51.2.4  2001/03/12 03:59:30  geraint
## SIGINT  (C-c C-c) now causes simulation data to be dumped to MTT.core.
## SIGQUIT (C-c C-\) as for SIGINT, then raises default SIGQUIT.
## SIGFPE  as for SIGINT, then raises default SIGABRT.
##
## Revision 1.51.2.3  2001/03/07 04:06:55  geraint
## Irix: catch SIGFPE and write data before aborting (.exe).
## GNU/Linux: nada.
##
