--- Comment #15 from Iain Sandoe <iains at gcc dot gnu.org> --- by coincidence (triaging Darwin bugs at the moment) I was looking at this last night. An alternative, for platforms with math_errhandling and which use MATH_ERREXCEPT, (Darwin and a couple of others) could be to arrange for the tests to check the exception conditions when MATH_ERREXCEPT is set in math_errhandling and errno otherwise (I was thinking of looking into adding an extra field to the TEST macro for the exception bit value). However, if there's not 1:1 mapping (it could be that the exception bits are more fine-grained), then perhaps better to skip the test and add a similar one that is keyed off the exception bits instead.
