I mean literally. An article [0] reminded me of the fact that I enable -Wall in 99% of time -- and most packages I use have it enabled too.

It's well known that -Wall doesn't enable all warnings, but a subset of warnings that

* are well accepted by the community

* rarely produce false positives

Well, they look like good reasons to enable the warnings by default. Same goes for -Wcompat, except that it is not as popular as -Wall. Seeing potential problems when compiling code is far less of a pain than leaving breakages unnoticed.

Am I missing some obvious reason not to do this?
