The NULL from libstdc++:
# if defined __GNUG__ && \
   (__GNUC__ > 2 || (__GNUC__ == 2 && 
__GNUC_MINOR__ >= 8))
#  define NULL (__null)
# else
#  if !defined(__cplusplus)
#   define NULL ((void*)0)
#  else
#   define NULL (0)
#  endif
# endif
#endif

which way you want to go depends on your tolerance of __null.
