Subject: SSL: silenced GCC warnings when building with BoringSSL.
X-Git-Tag: release-1.23.2~20
X-Git-Url: http://www.kaiwu.me/postgresql/commit/static/gitweb.js?a=commitdiff_plain;h=5071bc0bcf18c2eade9d452b27d92bee341dd053;p=nginx.git

SSL: silenced GCC warnings when building with BoringSSL.

BoringSSL uses macro stub for SSL_CTX_set_ecdh_auto that expands to 1,
which triggers -Wunused-value "statement with no effect" warnings.
