+# Update 4/4/2002 - Regardless of which opinion you have, you would
+# probably have to agree that gdb is currently behaving as designed,
+# in the absence of additional code to not stop in functions used
+# internally by the compiler. Since the testsuite should be checking
+# for conformance to the design, the correct behavior is to accept the
+# cases where gdb stops in memcpy/bcopy.
