Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Plus changes to __LDBL_*__ macros for IBM double double are highly undesirable at this point, there is a lot of code in the wild that checks the exact values of these macros, so e.g. changing __LDBL_MANT_DIG__ from 106 to something else would break quite a bit of code, including libstdc++, libgfortran etc.
