--- Comment #2 from Alain Knaff <gcc at misc dot lka.org.lu> 2011-07-14 17:38:59 UTC --- Created attachment 24756 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=24756 Test program for const warning bug > the warning is correct, see http://c-faq.com/ansi/constmismatch.html Thanks for this link. This does indeed confirm what I said, in much less words than I needed. Moreover, it points out that the issue doesn't exist in C++. However, it doesn't explain why the issue still present in C. Any insights into this question? If this is just to keep some paper-pushers happy, maybe we could keep the current behavior as the default, but have a -W flag to make gcc mimic g++'s behavior?
