>Description:
        emulators/qemu (qemu-0.12.3) produces an (linker) undefined
        symbol error when linking libqemu.a (isunordered is undefined).

>How-To-Repeat:
        I use pkg_comp with libkver and NetBSD 4.0 release sets installed
        (except the x* sets, I use X11_TYPE=modular).

        In that environment, with the current version of qemu,
        expect to see ...

        There were a lot more similar compile warnings earlier
        in the build log that I don't believe it is necessary
        to include here (looked to be just the same thing over and over).

>Fix:
        I assume isunordered() is some new lib function that doesn't
        exist on NetBSD 4.0 - to fix this, I guess that either qemu
        needs to be made to stop calling it, or a compat function needs
        to be provided.

        Alternatively, if this package isn't really intended for
        NetBSD 4.0, perhaps a NOT_FOR_PLATFORM would be an easier
        fix...

        If that is done, it would also close PR 42176 - the build
        that detected the error reported here was my attempt to see
        if the newer qemu happened to have a fix for that problem
        (unfortunately the problem above appears earlier in the
        build, so I never got to find out...)
