thre is *no* ABI problem that you afraid, we can use different
_CTYPE_* definition
between new and old table by split it src/inlucde/ctype.h and
libc/compat/include/ctype.h trick.
or we can easily change old _CTYPE_* stuff renameing _COMPAT_CTYPE_*.

i don't think we need re-ordering ifdef, reason is above.
we have to go with _CTYPE_* == _RUNETYPE_* ordering from the start.

i'll catch up my patch to recent -current codebase, in one week or two.
