The -fno-inline-functions option is ignored by the tree inliner in gcc-3.4 for
static functions, even at -O2 where according to the manual it shouldn't be
enabled in the first place. For example:

static int local (int a)
{
  return a;
}

int global (int a)
{
  return a;
}

int test (int a, int b)
{
  return local (a) * global (b);
}

Compile with "-O2" or "-O3 -fno-inline-functions" and see that local() is
inlined into test(), but global() is not. This may be intentional, but it is
confusing since the manual suggests it should be otherwise, in which case this
is a documentation bug.
