 65  NOTES: Most functions exported by ordinal seem to be superfluous.
 66  The reason for these functions to be there is to provide a wrapper
 67  for unicode functions to provide these functions on systems without
 68  unicode functions eg. win95/win98. Since we have such functions we just
 69  call these. If running Wine with native DLLs, some late bound calls may
 70  fail. However, it is better to implement the functions in the forward DLL
 71  and recommend the builtin rather than reimplementing the calls here!
