Actually sizeof(void) in gcc gives you one.  void has no size in the ANSI standard, but in gcc it does.  Having sizeof(void) give you something, and the having the ability to dereference void are apparently independent.  In any case, zlib needs to abide by the ANSI standard, so it won't depend on that gcc-unique extension to the standard.
