--- Comment #2 from Iain Sandoe <iains at gcc dot gnu.org> ---
on gcc110:

this fails:

$ cat ~/hello.c

extern int printf (const char *, ...);

int main (int ac, char *av[])
{
  printf ("here we are");
  return 0;
}

this does not:

$ cat ~/foo.c

void g (void *);

void foo (void) { g ("xyzzy"); }

so maybe something happens with the builtin string handling that does not
affect regular funcs.
