Hi everyone, [Tom]> I think most long term developers really just want the warnings for two things. Things that are undefined behaviour, and things that are likely a typo... I don¹t mind keeping -Wall with the current meaning, and not deprecating it. I, as a long term developer who has been developing for over 30 years, and in C/C++ for over 20 years, using GCC since 2.95 came out, do wish that there was a -Weverything flag that enabled all -W* toggle warnings. Why? Because I use GCC as a lint-like tool. I like to be able to see what warnings my code generates, vet those warnings and vet my code, then decide to disable the warning or fix my code. I deeply appreciate that GCC has taken on incorporating (sensible) lint-like functionality into the compiler itself, which uses -Wfoo toggles. (I can even appreciate that -Wall is "select popular warnings", and -Wextra is "select additional less popular warnings".) Right now, I have a command-line for GCC g++ that is very, very, very, very long, because I enable the warnings I know about. But I may have missed one or two. And more may come out with the next version of GCC that I am unaware about. I wish I had a -Weverything flag. As long as I'm making wishes, I also wish warnings were emitted like this: test.cpp:6: -Wunused warning: unused variable 'u' ...rather than... test.cpp:6: warning: unused variable 'u' Just my $0.02.
