--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
clang does this as a pedwarn:
<source>:20:12: warning: ISO C++20 requires return type of selected
'operator==' function for rewritten '==' comparison to be 'bool', not 'int'
[-Wrewrite-not-bool]
    if (*b == *d) {
        ~~ ^  ~~


I don't know if it makes sense now to change GCC to do a pedwarn instead of an
error.
