If you can reproduce these also with plain "cc -Ae", it would be good if
you could investigate details, such as:
- what can be done to use 64-bit constants in preprocessor directives with
    this compiler?
  - where does the sign bit of the negative zero get lost?
  - does have_minus_zero () actually evaluate to true?

Nope, no need. Removing +Onofltacc from the compilation flags allows the test
to pass correctly.

Cheers,
        Gary
