+Subject: [PATCH] build: resolve compile abort in libxt_limit on RHEL5
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+	libxt_limit.c: In function 'print_rate':
+	libxt_limit.c:124: error: 'INFINITY' undeclared (first use in
+	this function)
+
+The default mode of glibc-2.15's <features.h> sets
+"-D_POSIX_C_SOURCE=200809L", and therefore "-D_ISOC99_SOURCE". However,
+on þe olde RHEL 5's glibc-2.5, it only has "-D_POSIX_C_SOURCE=200112L".
+
+Explicitly draw in the definition of INFINITY by always defining
+_ISOC99_SOURCE. By doing this, we are moving off of the default set, so
+_BSD_SOURCE also needs to be explicitly set to get at IFNAMSIZ that is
+used in xt_hashlimit.h.
