+       * configure.ac: Update GMP check. Check for the function
+       mpn_sec_div_r, available since GMP-6.0.0.
+
        * testsuite/rsa-encrypt-test.c (test_main): Fix allocation of
        decrypted storage. Update test of rsa_decrypt, to allow clobbering
        of all of the passed in message area.
