i figured a good starting point might be to clean-up the o/p of
   gcc -Wall...

remember that one of the goals is to have these changes integrated into
the master xfree tree...   i don't know how they are about "needless"
changse.
   
   what is normally done for printfs of addresses? eg
   
   	printf("%d", ptr - otherptr);


%p is for pointers.  however, "ptr - otherptr" has a return value of
size_t or is it ptrdiff_t?  ummmm for that we don't have a good solution
unless there is an <inttypes.h> for it... but i don't see one..
