Well, the following functions are all exported by cygwin1.dll (listed in

localeconv  (declared in /usr/include/locale.h)
setlocale   (ditto)
mblen       (declared in /usr/include/stdlib.h)
mbstowcs    (ditto)
mbtowc      (ditto)
wcstombs    (ditto)
wctomb      (ditto)

The only function 'missing' from your list is mbcurmax().  But, if you
look at the file mbcurmax.c in the djgpp source code, that file just
declares the variable "__dj_mb_cur_max".  Well, cygwin's stdlib.h
declares __mb_cur_max, and that symbol is exported by cygwin1.dll
(listed in cygwin.din).

So, it looks like the *only* thing necessary is just my tiny little
change to newlib/libc/locale/locale.h == /usr/include/locale.h
