Re: [libvirt] [PATCH] Fix compilation of legacy xen driver with Xen 4.2

In Xen 4.2, xs.h is deprecated in favor of xenstore.h. xs.h now contains #warning xs.h is deprecated use xenstore.h instead #include <xenstore.h> which fails compilation when warnings are treated as errors. Introduce a configure-time check for xenstore.h and if found, use it instead of xs.h. --- configure.ac | 2 ++ src/xen/block_stats.c | 6 +++++- src/xen/xs_internal.c | 6 +++++- 3 files changed, 12 insertions(+), 2 deletions(-)
