+ - (dtucker) [configure.ac kex.c key.c myproposal.h] Test for the presence of
+   NID_X9_62_prime256v1, NID_secp384r1 and NID_secp521r1 and test that the
+   latter actually works before using it.  Fedora (at least) has NID_secp521r1
+   that doesn't work (see https://bugzilla.redhat.com/show_bug.cgi?id=1021897).
