Ok... here's the summary:

Hopefully locale support will build when cross compiling now.  Collation is
  still not supported, but that's what I'm currently working on.  In the
  next couple of days, I'll probably put up a couple of files for download
  that will save people the trouble of generating all the glibc locales.
Added *wprintf functions, although they currently don't support floating
  point.  That will be fixed when I rewrite _dtostr... or possibly before.
Added the wcsto{inttype} functions.
Added iconv() and a mini iconv utility.  The require locale support and
  only provide for conversions involving the various unicode encodings
  { UCS-4*, UCS-2*, UTF-32*, UTF-16*, UTF-8 }, the 8-bit codesets built
  with the locale data, and the internal WCHAR_T.
