This should be provided by the compiler, eventually.

UCSProc:
TYPE =
PROC [
msg: UNSPECIFIED, signal: SIGNAL ANY RETURNS ANY, frame: PrincOps.FrameHandle];
RegisterUncaughtSignalHandler:
PROC [proc: UCSProc]
RETURNS [old: UCSProc];
Registration mechanism for the global uncaught signal handling function.
InformationalSignal:
SAFE PROC [signal:
SIGNAL];
This is a temporary kludge that provides a minimal informational signal mechanism.
