Who defines __fhnd_info[_NFILE] ?

[Bill Baxter]

It appears in these two places:
phobos/std/stdio.d:321:    if (__fhnd_info[fp._file] & FHND_WCHAR)
phobos/std/c/stdio.d:103:    extern ubyte __fhnd_info[_NFILE];

But I can't figure out how it's supposed to get resolved.

A recent change to Tangobos and/or Tango made it so the symbol isn't 
getting found any more at link time.  I can't figure out how to fix it.

Help appreciated.
