Sure, but my point is that -Werror is not always a good thing. You have a struct with 3 ints and then you add a bool and the compiler decides to pad the struct up to the size of 4 ints. When you have twelve of those structs obeying the -Werror is basically saying "stop the train! There's 36 bytes of wasted memory on the tracks", which is kinda ridiculous. I think it should be a note, not a warning, but until then -Werror is kinda broken for me.
You can selectively disable that particular warning with '-Wno-xxxx'. That way you get the ease of -Werror and you can get rid of those warnings that get in your way.
Yes, that is one approach that may be useful for some more esoteric warnings.
All current compilers also have mechanisms to selectively ignore warnings via pragmas, like '#pragma GCC diagnostic ignored "-Wfoo"' in clang and GCC, which can be used to suppress instances of false positives of otherwise useful warnings.
