The dll header file defines the functions using the WINAPI definition, which 
appears to map to __stdcall, so I thought the compiler already had the right 
information in this regard.  I'll research over at MSDN; thank you.

I posted an apology and a correction within 10 minutes after posting an 
attachment containing build products, which caused its massive size.  I can't 
blame you for busting my chops anyway; it was a bone-headed oversight.
