This is certainly the case with the MS compiler, who even at lower warning
levels tends to make spurious comments about your code (not really warnings at all).
At least it gives me the #pragmas I need to silence them.
Indeed. It's a shame that gcc doesn't provide a good 'prama disable'.
However with gcc (and possibly other compilers), building w/ -Wall
-Werror is tenable, and is usually the Right Thing. We have done this on the last several (extremely large) projects I have worked on.
In my experience it's the Right Thing for certain common coding styles, but completely wrong for others.
Hence 'usually'. My coding style apparently falls amongst the common. For example, GCC has a
warning about a derived class whose base doesn't have a virtual dtor. It's actually *impossible* (not just inefficient or convoluted) to implement is_polymorphic without generating that warning.
Interesting. I'm obviously flaunting my ignorance, but I didn't realize that inheriting from a class sans virtual dtor was ever a Good Thing. I'll have to read up on the issues WRT is_polymorphic. Jon
