definition of NULL correct?

[Greg Troxel <gdt%ir.bbn.com@localhost>]

We define NULL as "(void *)0" rather than "((void *)0)", and that causes

  sizeof NULL

to fail.


I found this in libunistring:

  https://savannah.gnu.org/support/index.php?106973

Here is an example program, which fails to build on NetBSD 5 (i386).


Some of the gnulib people think that this is a failure of NetBSD to
comply with POSIX 2008.

----------

#include <stdlib.h>
#include <stdio.h>

int
main()
{
  printf("null size is %zd\n", sizeof NULL);

  return 0;
}
