perf: Fix missing strndup declaration

fweisbec · fweisbec · commit ff9ae1babd8c · 2011-03-04T01:17:18.000+01:00
&lt;ctype.h&gt; is included first without _GNU_SOURCE, so it ends up
including &lt;string.h&gt; without declaring strndup(). And further
&lt;string.h&gt; declarations, even with _GNU_SOURCE defined, are
of course without effect.

Therefore:

	util/strfilter.c: Dans la fonction «strfilter_node__new» :
	util/strfilter.c:134: attention : déclaration implicite de la fonction « «strndup» »
	util/strfilter.c:134: attention : incompatible implicit declaration of built-in function «strndup»
	make: *** [util/strfilter.o] Erreur 1

Just don't include ctype.h as it doesn't appear to be necessary
anyway.
