    I was not able to tune gcc-14 properly using CFLAGS to apply this workaround when using gcc-13 as the bootstrap compiler but the attached patch worked for me which of course can't be used in the actual package.

    It should be possible to add -fno-fold-mem-offsets to DRIVER_SELF_SPECS on m68k. However, I currently don't understand how the syntax works. I'll
    ask the Gentoo people who have done this.
    This didn't work, unfortunately [1]. However, I used Gemini to come up with the attached patch which fixes the glibc build problem for me. Can you include it instead?
    Thanks,
    Adrian

    For clarification, this patch should be applied on m68k only, see [1].

    I'm going to test this proposed patch now [1].
