+Use the official _BSD_SOURCE feature test macro instead of the meaningless
+HAVE_STRSEP macro in order to detect the availability of strsep().
+
+This allows toolchains supporting strsep() to use it instead of the custom
+implementation from dhcpdump, which also avoids the following error with some
+toolchains:
+
+	In file included from dhcpdump.c:30:0:
+	dhcpdump.c: At top level:
+	strsep.c:65:23: error: register name not specified for ‘delim’
+	  register const char *delim;
+	                       ^
