This implements a fix similar to what the FreeBSD headers do to avoid breaking code (they provide a static inline extern(C++) overload for the old signature). This provides a deprecated extern(D) overload for the old signature. The extern(C) overload now matches the new signature. The changes have been versioned so that they only affect FreeBSD 14 and newer. Technically, if someone used Cmp when declaring their function for qsort_r, this would still break them (though with a compilation error that should be easy to fix rather than silent breakage or a crash), but I don't really see a way around that, and Cmp is not part of the POSIX API, so no one would have a clue that it was a thing without digging through the bindings. Arguably, we should make it private, since it's not part of POSIX, but I haven't done anything with that in this commit. My guess is that in reality, no D programs are both written to use qsort_r and run on FreeBSD (outside of the druntime tests), but this way, they won't break unless they use Cmp to declare their comparator function. They'll just get a deprecation message that they should update their code. Regardless, we have to change the signature for FreeBSD 14 for it to work, and this does that. https://github.com/dlang/dmd/pull/16405 -- |
