[Bug target/22099] New: builtin_setjmp gives duplicate labels

[hebisch at math dot uni dot wroc dot pl]

The following program, when compiled with -fPIC option (on by
default on Darwin) gives me duplicate label in assembler
output:
extern int printf(const char *, ...);

struct { int a[5];} jmp_buf;
void
f(void)
{
  void g(void)
  {
  }
  if (__builtin_setjmp(&jmp_buf))
    goto l;
  g();
  printf("failed\n");
l:;
}

int
main(void)
{
  f();
  return 0;
}

I can see duplicate label "L00000000001$pb" in the assemble output.
Note that I have not set up full cross-compile environmet, I just
configured gcc for i686-apple-darwin target. The build failed,
but cc1 is built. 
This is a reduced test case. Original problem appeared in GNU
Pascal in native compiler on i686-apple-darwin host.
The problem is also present in gcc-3.3.6 (the label is called
L1$pb) and in gcc-3.4.4.
