I did already check it in.

Yes.  In c-torture/execute, you can get the same effect as the
dg-options line by creating 20000623-1.x with the contents

set additional_flags="-fno-strict-aliasing"
return 0

The advantage of doing it this way is you still get c-torture's cycle
through optimization levels.

In c-torture/compile, the same trick works but you have to say 
`set options="..."' instead of additional_flags.
