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