There is a difference: %lu is defined by C89, while %ll is only
codified by C9X.  GDB does not yet require a C9X compiler.

sizeof returns a value of the type `size_t'.  On a 64-bit host, size_t
is typically a 64-bit data type, and so is `unsigned long'.  (64-bit
Windows is an exception, because it uses a different programming
model.)
