A fresh checkout on a RHEL 6 machine with these packages: kernel-headers-2.6.32-405.el6.x86_64 glibc-2.12-1.128.el6.x86_64 failed to configure with this message: checking for linux/if_bridge.h... no configure: error: You must install kernel-headers in order to compile libvirt with QEMU or LXC support
Digging in config.log, we see that the problem is identical to what we fixed earlier in commit d12c2811:
configure:98831: checking for linux/if_bridge.h configure:98853: gcc -std=gnu99 -c -g -O2 conftest.c >&5 In file included from /usr/include/linux/if_bridge.h:17, from conftest.c:559: /usr/include/linux/in6.h:31: error: redefinition of 'struct in6_addr' /usr/include/linux/in6.h:48: error: redefinition of 'struct sockaddr_in6' /usr/include/linux/in6.h:56: error: redefinition of 'struct ipv6_mreq' configure:98860: $? = 1
I had not hit it earlier because I was using incremental builds, where config.cache had shielded me from the kernel-headers breakage.
* configure.ac (if_bridge.h): Avoid conflicting type definitions.

Pushing under the build-breaker rule, and backporting to v1.1.1-maint
This change breaks configure on any Fedora install I have, so I've had to revert it in master, since broken Fedora is more of a show stopper than broken RHEL6.
