no, no. we don't use old ctype table anymore.
LC_CTYPE database doesn't contain old ctype table info.

current implementation, _ctype_ table is generated from Rune + wctob,
please read carefuly src/lib/libc/locale/rune.c.
yes, it is too much cost, but workaround for following PR:

http://www.freebsd.org/cgi/query-pr.cgi?pr=116363&cat=gnu
http://mail-index.netbsd.org/source-changes/2007/09/29/0000.html

keep _CTYPE_* and _RUNETYPE_* is same layout is for reducing this runtime cost.
