What did you say you did about the Pascal calling convention?  Was that 
you?  Someone explained previously here you have to reverse the order of 
the arguments or something like that, but I can't find the message.

I thought I'd take a shot at porting the header, but all I get is
  Error 42: Symbol Undefined _WTOpenW at 12

I tried the various combinations of making the import lib with /system 
and without.  And making the prototypes extern(Windows) vs extern(C). 
No luck so far.

The entry in WINTAB32.DEF looks like this:
WTOpenW at 12                      @1021

And the prototype i'm using looks like this:
HCTX WTOpenW(HWND, LPLOGCONTEXTW, BOOL);
