This change is wrong; if NULL is defined to 0 (as permitted by the C
standard), this will end up passing an int to the function instead of
the right kind of pointer, and chaos may ensue, especially if int and
char * have different sizes.

Thus, you must use (char *)NULL.

Many other hunks in this patch have the same problem.
