From 17ed3253fc98bcca59d70531a4d81b3be75dc7ea Mon Sep 17 00:00:00 2001

Subject: Add const to global pointers to strings.

When a global pointer is not declared as constant, gcc will put it in
memory. Getting the address of the string it points to requires loading
the address of the pointer and then loading the pointer. When the pointer
is declared constant, the address of the string is loaded directly.
