// On Linux NULL is defined as a special type '__null'. Assigning __null to

// pointer is stored as integer value. On some platforms, sizeof(intptr_t) >
// sizeof(void*), so here we want something which is integer type, but has the

// AIX also needs a 64 bit NULL to work as a null address pointer.
// Most system includes on AIX would define it as an int 0 if not already defined with one
// exception: /usr/include/dirent.h will unconditionally redefine NULL to int 0 again.
// In this case you need to copy the following defines to a position after #include <dirent.h>
