+  In c3f01c72b303cbbb0cc8983120677edee2f3fa4b the use of the ucontext api
+  in the main program was removed, and with it the configure check for it.
+  However, the ucontext api is still used in the "explicit_bzero" test and
+  thus this test still needs to be in place.
+  See also: https://bugs.gentoo.org/838172
+* configure: Restore the functionality of the '--disable-symvers' switch.
