--- Comment #11 from Jonathan Wakely <redi at gcc dot gnu.org> --- The last patch cannot be backported to gcc-15 without the series of patches for PR110739 which are too invasive to backport. The _M_a_A, _M_b_B and _M_p functions could be rewritten on the branch to use _M_locale_fmt but it would be a new patch, not a backport.
