In the course of getting the NS port compiling in 64-bit mode, some  
other developers and myself discovered some format - arg mismatches in  
printfs.  XINT and XUINT return EMACS_INT which can be a long under  
LP64.  I'd like to replace places that use %d in the code with %ld,  
and cast the argument to (long) to avoid issues in 32-bit mode.  This  
has been checked in for the NS port; the patch attached here does this  
in common code.  Does anyone think this should be done differently?   
Else I'll check it in as well.

thanks,
Adrian
