Log message:
Stash the environment pointer we get from realloc() instead of just
setting a flag.  That way when we are called again we can be sure
to realloc() the right thing, regardless of the current value of
environ.  When the stashed value != environ (or when we are called
for the first time), copy the existing entries from environ and set
environ to the new value.  OK deraadt@, beck@, djm@
