I hope you will understand that both approaches (wapper approach and
non-wrapper approach) are _compatible_.

In Cygwin-1.5.20-1 on Windows XP,
fhandler_disk_file::readdir() at winsup/cygwin/fhandler_disk_file.cc
does not use FindNextFileA, one of ANSI WIN32 APIs, anymore.  It use
so-called undocumented APIs which are Unicode-base.  You have
implemented your approach here a little, haven't you?

And the UTF-8 Cygwin still works very well ;-)

Wrapper functions do _nothing_ where wide characters are used.
It is sys_wcstombs that converts Unicode to UTF-8 here.

The cygwin programs can enjoy UTF-8 _now_ with the UTF-8 patch,
and someday in the future when UTF-8 is supported natively,
you can delete wrapper functions which are not used anymore then.
