Thanks, I'll fix it. For those of you wondering what we are talking about, 
the Win32 API documents a bunch of functions operating on narrow strings, 
but they are really implemented as macros.  So depending on macro 
definitions, they may unexpectedly start trafficking in wide char strings 
rather than narrow char. A trap for the unwary. The fix is to avoid the 
macro names, and use the names of the functions being forwarded to.
