+         There are two versions of regex.  The older (stable) version has
+         been in uClibc for quite a long time but hasn't seen too many
+         updates.  It also has some known issues when dealing with uncommon
+         corner cases and multibyte/unicode strings.  However, it is quite
+         a bit smaller than the newer version.
+

+         support, then stick with the old version (and say Y here).
+         Otherwise, you should use the new version (and say N here).
