[Dnsmasq-discuss] [PATCH] remove self assignment on variable creatrion on stack

[Donald Sharp]

In C when declaring a variable on the stack, it is assigned
what ever happens to be on the stack at the place the variable
is accessed in memory from previous usage.  Let's explicitly call out a
value instead of using whatever happens to be on the stack
at the point of creation of the sav value.
