In variadic functions we still do the cast. In POSIX, it's not
necessary, since NULL is required to be of type 'void *', and 'void *'
is guaranteed to have the same alignment and representation as 'char *'.
However, since ISO C still doesn't mandate that, and moreover they're
doing dubious stuff by adding nullptr, let's be on the cautious side.
Also, C++ requires that NULL is _not_ 'void *', but either plain 0 or
some magic stuff.

when the signal handlers are restored.

integer.
* src/chpasswd.c: Use the SCALE macro instead of (24L * 3600L)
for the values to be set in /etc/shadow.

read-only).
