5565 # This is a silly "warning" that basically just alerts you that the

5567 # supposed to, instead of not following it like old buggy versions
5568 # did. There's absolutely no reason to turn this on.

5572 # It's commonly useful to pass |this| to objects in a class'
5573 # initializer list. While this warning can catch real bugs, most of
5574 # the time the constructors in question don't attempt to call methods
5575 # on the passed-in pointer (until later), and annotating every legit
5576 # usage of this is simply more hassle than the warning is worth.
5579 # C4503: 'identifier': decorated name length exceeded, name was
5581 # This only means that some long error messages might have truncated
5582 # identifiers in the presence of lots of templates. It has no effect
5583 # on program correctness and there's no real reason to waste time
5584 # trying to prevent it.
5587 # C4611: interaction between 'function' and C++ object destruction is
5589 # This warning is unavoidable when using e.g. setjmp/longjmp. MSDN
5590 # suggests using exceptions instead of setjmp/longjmp for C++, but
5591 # Chromium code compiles without exception support. We therefore have
5592 # to use setjmp/longjmp for e.g. JPEG decode error handling, which
5593 # means we have to turn off this warning (and be careful about how
