Subject: build: resolve compile abort in libxt_limit on RHEL5
X-Git-Tag: v1.4.16.3~1
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9921f2b9a241750e4730fc7d486687c6a32779f4;p=thirdparty%2Fiptables.git

build: resolve compile abort in libxt_limit on RHEL5

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.
