New Revision: 5062
URL: http://trac.nginx.org/nginx/changeset/5062/nginx

Log:
Merge of r5014, r5015, r5016, r5030: geoip ipv6 support.

*) Configure: fixed style of include directories.

*) Configure: fixed GeoIP library detection.

*) GeoIP: IPv6 support. When using IPv6 databases, IPv4 addresses are
looked up as IPv4-mapped IPv6 addresses. Mostly based on a patch
by Gregor Kali?\197?\161nik (ticket #250).

*) GeoIP: removed pseudo-support of "proxy" and "netspeed" databases.
