Return to _wctype.c CVS log

Up to [cvs.NetBSD.org] / src / lib / libc / locale

1. split runetype_local.h -> runetype_file.h
   and remove renameing _Rune* -> _NBRune* namespace protection.

   FreeBSD traditionaly exposes struct _Rune* in runetype.h
   which included by ctype.h. it may cause conflicting type error
   in our cross build process, former we use renaming namespace
   to avoid this problem, now i reworked more resonable way.

2. merge rune_local.h to runetype_local.h, and remove it.
3. split bsdctype.h -> bsdctype_{file,local}.h
