PatchSet 5635 
Date: 2007/09/21 09:08:24
Author: amosjeffries
Branch: squid3-ipv6
Tag: (none) 
Log:
Fix fallout from actual FreeBSD compile tests.

 - FreeBSD 6.2 does not seem to provide _res_ext form IPv6 support
   on the native resolver

 - autoconf 2.59 contains a regression which blocks parametized macros
   ie AC_DEFINE([FOO(i)],[__bar = i],[goes all fubar])

Members: 
	NOTES-IPv6:1.1.2.67->1.1.2.68 
	bootstrap.sh:1.17.4.2->1.17.4.3 
	src/dnsserver.cc:1.7.4.20->1.7.4.21

 	I've found the time to sort it out (I think) and it appears to be going
 	well enough for some detailed tests.
 
+2007-09-21:
+	Due to a regression bug in autoconf 2.59 some OS may encounter compilation errors
+	when IPv6 extensions are not available via _res_ext from the system native
+	DNS resolver. This can be resolved by upgrading to autoconf 2.61 or later.
+	Systems where _res_ext is provided should not encounter this problem.

 PROBLEM: Testers report that "using WebDAV against my Squid-accelerated Apache gives
 	 all sorts of odd timeouts" but tester unable to spend time tracing the cause.
