Details:

Using gcc version 4.1.1 20070105 (Red Hat 4.1.1-51)

The "if and how we can waste code space" fails due to a bug in the test code.
Cose examination of the test reveals that each of the
tested scenarios fails with:

  error: label at end of compound statement

Changing the test code in configure.in from:

  int foo(int x)
  {
    if (x) {
    label1:
      asm("$i");
    label2:
    }
    return (&&label2)-(&&label1);
  }

to:

  int foo(int x)
  {
    if (x) {
    label1:
      asm("$i");
    label2:
      ;
    }
    return (&&label2)-(&&label1);
  }

fixes the test code syntax error and allows the tests to run.

A patch file is attached.

This fix allows the dynamic code generation to occur.
