Hi Dale,

> Don't suppress no-dead-strip for used static functions.
This contradicts with the comment of function. Please update it. Also,
it seems, that gcc (at least, apple gcc 4.0.1) does not look to
linkage in this such situation at all:

void bar();

static int __attribute__((used)) a;

static void __attribute__((used)) foo()  {
  bar();
}

compiles into:

        .text
        .align 4,0x90
.no_dead_strip _foo
_foo:
        pushl   %ebp
        movl    %esp, %ebp
        leave
        jmp     L_bar$stub
.no_dead_strip _a
.lcomm _a,4,2

Note, that both foo and a are 'used' here
