Comment (by simonmar):

 Good catch, I suspected it might have been something to do with that
 patch.

 Though I don't like the fix much.  Something like this would be better:

 {{{
 #if SIZEOF_LONG == SIZEOF_VOID_P
 #define UNIT 1UL
 #elif SIZEOF_LONGLONG == SIZEOF_VOID_P
 #define UNIT 1ULL
 #else
 #error ...
 #endif
 }}}
