Thanks > http://sylvestre.ledru.info/0001-Enable-warning-Wreturn-type-by-default.patch I don't think most of the testsuite changes in this patch should be needed, and we should be conservative about changing existing testcases because of the risk that it affects what they test. Most of the changes seem like they would only have been relevant for the previous version that enabled -Wmissing-return warnings by default. The change to gcc.dg/c90-impl-int-1.c is simply wrong - the specific point of that testcase is to test various cases of implicit int, so you can't add explicit int return types to it. You need, obviously, the new tests for how -W(no-)missing-return and -W(no-)return-type work and what the defaults are. Existing tests should only need to be changed if they do in fact fail with the compiler patch applied.

I updated the patch (including the gcc.dg/c90-impl-int-1.c change): http://sylvestre.ledru.info/0001-Enable-warning-Wreturn-type-by-default.patch For information, the number of files modified by this commit dropped from 1298 to 818. Thanks, Sylvestre

Are you sure that's the right patch? * It seems to be missing the new testcases, which are a necessary part of the patch. * The first few testcase changes I looked at in the patch still don't make sense to me. They are changing int return types to void, or adding "return 0;", which should not be needed with the defaults as I understand them - the warnings for those should be the "control reaches end of non-void function" which I thought was being left off by default. If those are getting warnings (for C) without the changes, there's something I still don't understand about what this patch is doing and why it's meant to be safe. Could you clarify - in terms of source code constructs, not option names - which cases your patch would or would not cause to receive warnings by default for C?
