I think you should only use "0", since this is a magic token for C compilers
that can be interpreted either as an integer or as a pointer, depending on
context.

Anecdote: on very old machines, a 0 pointer translates to an internal
representation that isn't made of N bits set to 0, where N is the pointer
size used by the CPU. That's because on such architectures, 0 is a valid
address, while things like 0xFFFFFFFF are not.

I'm not certain that we support these machines in FreeType anyway, since we
tend to use "memset( record, 0, sizeof(*record) )" a lot today to clear
structures :-)
