Subject: Make Configure add the configuration options that it was copmiled
X-Git-Tag: OpenSSL_0_9_5beta1~49
X-Git-Url: https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff_plain;h=fb044c592d58da1ba2f8eb137ccf99c484879679;hp=4328d51d08e89cf9d46836a2875b3d545711a4d8

Make Configure add the configuration options that it was copmiled
with.

Currently, those defines are protected with a OPENSSL_EXCLUDED.  That
may not be the best strategy, but it will do for now.
