that our headers are not built with __GNUC__ and __STRICT_ANSI__. __extension__ had some weird (and buggy) behaviours when nested which make it a risky proposition for general usage in our header files. Better to disallow -ansi, -std=c99, and similar gcc options when building against Xen headers. Signed-off-by: Keir Fraser <keir.fraser@citrix.com>
