[nginx] svn commit: r4551 - trunk/auto

[ru at nginx.com]

Author: ru
Date: 2012-03-21 15:35:05 +0000 (Wed, 21 Mar 2012)
New Revision: 4551
URL: http://trac.nginx.org/nginx/changeset/4551/nginx

Log:
The addition of $tcpinfo_* variables has broken the build on Linux
systems with glibc versions prior to 2.7.  Fixed this by checking
the existence of "struct tcp_info" members during configuration.
