Seems like netfilter is missing an include <limits.h> ...

Either you fix it by hand in your netfilter_ipv4.h header, which is dirty and not a long-term solution, or you can insert "#include <limits.h>" in haproxy sources, let's say in include/common/compat.h for instance, as I think it will be loaded by all other files.

If this works, please drop us a mail with the patch with a small comment, I'll merge it indicating it fixes build on this distro.
