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