Subject: [PATCH]  - (dtucker) [configure.ac
 openbsd-compat/openssl-compat.{c,h}] Add    RSA_get_default_method() for the
 benefit of openssl versions that don't    have it (at least
 openssl-engine-0.9.6b).  Found and tested by Kevin Brott,    ok djm@.

  - (tim) [contrib/caldera/openssh.spec] Use CFLAGS from Makefile instead
    of RPM so build completes. Signatures were changed to .asc since 4.1p1.
