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!
