I'm trying to play around with windows and such.  I've encountered an error
I can't figure out.  Here
is the stuff:

#include <exec/types.h>             
#include <intuition/intuition.h>    
                                    
struct IntuitionBase *IntuitionBase;
struct Window *Window;

void OpenLibrary();                            
                                               
if (!(IntuitionBase = (struct IntuitionBase *) 
   OpenLibrary("intuition.library")))          
 {                                             
 printf("Could not open intuition.library.\n");
 close_junk();                                 
 exit(FALSE);                                  
 }

This ain't working.  Manx 5.0d tells me that there's an invalid type conversion
in the if statement, right on the second close paren after the actual 
OpenLibrary() call.  I thought maybe it was that I was passing it an old 
version number (I was passing 0L as the version number right after the first
arguement), but taking it out didn't make a bit of difference.  What am I 
missing?
Thanks,
