I don't understand how you implemented the intrinsic
functions for signal.  In iresolve.c, you have

+  if (handler->ts.type == BT_INTEGER)
+    {
+      if (handler->ts.kind != gfc_c_int_kind)
+       gfc_convert_type (handler, &f->ts, 2);
+      f->value.function.name = gfc_get_string (PREFIX("signal_int"));
+    }
+  else
+    f->value.function.name = gfc_get_string (PREFIX("signal"));

But, your function names are

+extern int signal_func (int *, void (*)(int));
+iexport_proto(signal_func);

+extern int signal_func_int (int *, int *);
+iexport_proto(signal_func_int);
