--- Comment #23 from Manuel López-Ibáñez <manu at gcc dot gnu.org> --- (In reply to David Malcolm from comment #21) > One other issue is that column numbering is rather a mess right now. From > my rich-location patch: > > /* Both gcc and emacs number source *lines* starting at 1, but > they have differing conventions for *columns*. > > GCC uses a 1-based convention for source columns, > whereas Emacs's M-x column-number-mode uses a 0-based convention. FWIW, GCC is right and Emacs wrong according to https://www.gnu.org/prep/standards/html_node/Errors.html Emacs could simply do the transformation itself.
