Module Name:
hackwc.cxx
Abstract:
This module contains the definition for a hack that allows me
to compare attribute names correctly.
The comparison of attribute names is binary (word by word);
I can't use WSTRING because it's comparisons are all based
on the locale, while this comparison is locale-independent.

Routine Description:
This function compares two counted wide-character buffers.
It compares word-by-word, rather than byte by byte.
Arguments:
String1 -- supplies the first wide-character buffer
Length1 -- supplies the number of wide characters in String1
String2 -- supplies the second wide-character buffer
Length2 -- supplies the number of wide characters in String2
Return Value:
a negative value if String1 is less than String2
zero if String1 equals String2
a positive value if String1 is greater than String2
