 2/* Sigcheck is similar to intrcheck() but sets an exception when an
 3   interrupt occurs.  It can't be in the intrcheck.c file since that
 4   file (and the whole directory it is in) doesn't know about objects
 5   or exceptions.  It can't be in errors.c because it can be
 6   overridden (at link time) by a more powerful version implemented in
 7   signalmodule.c. */
