Revision 1.26 2005-02-14 17:13:30 peter
* truncate log
Revision 1.25 2005/02/05 22:53:43 peter
* use typecasted sigactionhandler, needed for arm
Revision 1.24 2005/02/05 22:45:54 peter
* sigactionhandler fixed for arm
Revision 1.23 2005/01/30 18:01:15 peter
* signal cleanup for linux
* sigactionhandler instead of tsigaction for bsds
* sigcontext moved to cpu dir
