Possible bug with Builder 4

[Martijn Brinkers]

I tried,, and succeeded, to make a xerces dll with Builder4. The DomPrint
example worked when run on WinNT but not on Win98. The problem seems to
arise in :

void Win32TransService::upperCase(XMLCh* const toUpperCase) const
{
  _wcsupr(toUpperCase);
}
