It's possible that GCC's optimizer will do the right thing in either
case and it won't matter at all. I haven't tried compiling this patch
so I've not looked at the compiler output. But for the most part, using
"static" will save the few bytes of code needed to copy these strings
onto the stack (as well as the corresponding reduction in stack usage).
