[Python-Dev] test_coercion failing

[Flying Cougar Burnette]

I get the same ("0" then "+0") on my irix65 O2.  test_coerce succeeds
as well.

| What do you get?  WinTel prints "0" for the first and "+0" for the second.

| C89 doesn't define the results.

| C99 requires "-0" for both (on boxes with signed floating zeroes, which is
