Subject: Get IPv6 vhosts working (again ?).
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=840fcb47ac2d5dd2a1b1a51aee4ed4781b5c91ca;p=apache

Get IPv6 vhosts working (again ?).

There were a couple of bogus IPv4-specific comparisons which prevented
the data structures from being built correctly in ap_fini_vhost_config().
One of these (INADDR_ANY) can be easily rewritten to work with IPv6.  The
other (DEFAULT_VHOST_ADDR) isn't necessary for IPv6.  Note that this is
because we don't support the various flavors of _default_ that
Apache-1.3+KAME-patch supports.
