[libvirt] [PATCH] build: stop clang complaining about redefined typedefs
Clang's gnu99 mode is not quite the same as GCC's. It will complain
about redefined typedefs being a C11 feature, while GCC does not
complain and allows them in GNU99.

Technically a build breaker fix, but given my track record of
breaking the build today/yestday, lets have a reviewer approve :-)
