Subject: mod_ssl: follow up to r1861950: allow for OPENSSL_init_ssl() without autoconf.
X-Git-Tag: 2.5.0-alpha2-ci-test-only~1631
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d8fb24a0fd694766a64cda5633cac9b0d1056333;p=thirdparty%2Fapache%2Fhttpd.git

mod_ssl: follow up to r1861950: allow for OPENSSL_init_ssl() without autoconf.

For systems with no autoconf (eg. Windows), still check for and use
OPENSSL_init_ssl() based on OpenSSL version >= 1.1.0.

Usual LibreSSL gotcha, exclude LIBRESSL_VERSION_NUMBER from this new heuristic
since autoconf is likely available in this case.
