Comment:
Fixed by r36638.
- add has_negative_zero feature,
- fix print_n and say_n for the platforms failing the new
has_negative_zero
configure test
- enable the failing tests again
This print -0.0 is a long-standing problem and finally fixes [perl
#28170],
[perl #30737], [perl #19183], [perl #60312].
Note that special yet untested platforms, like arm might also fail
the "has_negative_zero" test and might fail the signbit workaround we use.
long double -0.0 will also need a workaround code like this.
There's a patch to generate the signbit() fallback at RT #30737.
Many thanks to Andy Dougherty for pointing me to the old tickets
and for the solution which was there for 5 years.
