Ups, missed that. No, with Fortran 2003's IEEE support we need it at some
point.

The question is when the option should be set, when it should be stricter (for
trapping math and signed zero) and when looser (allow to ignore the
parentheses) and what new option we need for this.
Additionally, one also needs to put that somehow into the manpage :-/
