--- Comment #2 from W E Brown <webrown.cpp at gmail dot com> --- (In reply to Marek Polacek from comment #1) > Patch on review. In the proposed patch, I respectfully recommend a slight rewording of the new pedwarn messages in gcc/cp/semantics.c and gcc/cp/typeck2.c: either s/only available with/available only with/ or s/only available with/unavailable without/ or s/only available with/requires/ would emphasize the required flag rather than focus on the feature's availability. (FWIW, of the above suggestions, the last ["requires"] seems to me the most direct and simplest to understand.) Thank you.
