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