Subject: Ignore unknown pragmas
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=9e346936d47a3a461f8ebaedabb2975bef3babf5;p=libevent

Ignore unknown pragmas

Since new compilers has new checks (like -Wdangling-pointer), and so to
avoid extra checks in cmake/autotools, simply suppress if the pragma is
unknown.
