Subject: SSL: fixed incorrect usage of #if instead of #ifdef.
X-Git-Tag: release-1.23.2~25
X-Git-Url: http://www.kaiwu.me/postgresql/commit/static/gitweb.js?a=commitdiff_plain;h=116a744799cf46916d1add01ad764718b7c53e9b;p=nginx.git

SSL: fixed incorrect usage of #if instead of #ifdef.

In 2014ed60f17f, "#if SSL_CTRL_SET_ECDH_AUTO" test was incorrectly used
instead of "#ifdef SSL_CTRL_SET_ECDH_AUTO".  There is no practical
difference, since SSL_CTRL_SET_ECDH_AUTO evaluates to a non-zero numeric
value when defined, but anyway it's better to correctly test if the value
is defined.
