Hi,
These earlier Darwin versions have “FP_≈” inside a comment in
architecture/{ppc,i386}/math.h, which is included by math.h which causes the
tests to fail.
The intent of the tests (i.e. to ensure that the library itself does not emit
non-ascii) is covered by other platforms, including later Darwin editions.
AFAICT, this issue was fixed from Darwin11 onwards (although I have not tested
every edition / looked for other possible non-ascii cases, in other headers).
Since there’s no expectation that the headers would ever be updated, and it
doesn’t seem worth applying fixincludes for this, let’s skip the tests on
versions with the issue.
Tested on powerpc-darwin9, x86_64-darwin10 and x86_64-darwin18.
OK for trunk?
