freebsd stable - Nov 2007 - if you see undefined symbol '__mb_sb_limit' on 6.x

The ctype fix for UTF-8 locale unfortunately introduced some
new symbols to libc. Therefore, binaries built on system with
that fix can not be used on older system. For that sake, the
fix is back-out for 6-STABLE. If you see undefined symbols
'__mb_sb_limit', please rebuild the affected binary. Everything
will be fine then. Binaries built between 20071025 and 20071030
will be affected by this.

Sorry for the inconvenience.

Can this symbol be actually leaved in the libc ? If not used by the
ctype.h, it would provide binary compatibility with all RELENG_6
systems in existence, not only the ones before 20071025 ?
