* Turns out that the "upper" half of the old (gcc2) libio - the C++ classes -

keeps its own idea about what a wchar_t is and that was still a short.
  This of course made the data structure of a streambuf incompatible with the
  "lower" half - the glibc part - causing (potentially all sorts of) crashes
  when these classes were used.
  This should fix the crash of gensyscalls when building haiku natively
  on a gcc2-haiku.
