regen/warnings.pl: Fix undefined C behavior

This fixes compiler warnings "performing pointer arithmetic on a null
pointer has undefined behavior"

There are several ways to fix this.  This one was suggested by
Tomasz Konojacki++.  Instead of trying to point to address 1 and 2, two
variables are created, and we point to them.  const is cast away.
