The fixincludes fix “math_exception” is being applied overly broadly, including many targets which don’t need it, like darwin (and probably all non-glibc targets). I’m not sure if it is still needed on any target, but because I can’t be absolutely positive about that, I don’t want to remove it. But it dates from before 1998.
In subsequent times (2000) it was bypassed on glibc headers, as well as Solaris 10. It was still needed on Solaris 8 and 9, which are (AFAICT) unsupported nowadays. The fix was originally bypassed on __cplusplus, which is the correct thing to do, but that bypass was neutralized to cater to a bug on Solaris 8 and 9 headers. Now that those are gone… let’s revert to the previous bypass. Bootstrapped and regtested on x86_64-apple-darwin23, where it no longer “fixes” the header unnecessarily. OK to push? FX
