# C4127: conditional expression is constant
# This warning can in theory catch dead code and other problems, but
# triggers in far too many desirable cases where the conditional
# expression is either set by macros or corresponds some legitimate
# compile-time constant expression (due to constant template args,
# conditionals comparing the sizes of different types, etc.). Some of
# these can be worked around, but it's not worth it.

# used by clients of class 'type2'
# This is necessary for the shared library build.

# C4275: non dll-interface class used as base for dll-interface class
# This points out a potential (but rare) problem with referencing static
# fields of a non-exported base, through the base's non-exported inline
# functions, or directly. The warning is subtle enough that people just
# suppressed it when they saw it, so it's not worth it.

# C4351: new behavior: elements of array 'array' will be default
# initialized
# This is a silly "warning" that basically just alerts you that the
# compiler is going to actually follow the language spec like it's
# supposed to, instead of not following it like old buggy versions did.
# There's absolutely no reason to turn this on.
"/wd4351",
# C4355: 'this': used in base member initializer list
# It's commonly useful to pass |this| to objects in a class' initializer
# list. While this warning can catch real bugs, most of the time the
# constructors in question don't attempt to call methods on the passed-in
# pointer (until later), and annotating every legit usage of this is
# simply more hassle than the warning is worth.
"/wd4355",
# C4503: 'identifier': decorated name length exceeded, name was
# truncated
# This only means that some long error messages might have truncated
# identifiers in the presence of lots of templates. It has no effect on
# program correctness and there's no real reason to waste time trying to
# prevent it.

# Warning C4589 says: "Constructor of abstract class ignores

# C4611: interaction between 'function' and C++ object destruction is
# non-portable
# This warning is unavoidable when using e.g. setjmp/longjmp. MSDN
# suggests using exceptions instead of setjmp/longjmp for C++, but
# Chromium code compiles without exception support. We therefore have to
# use setjmp/longjmp for e.g. JPEG decode error handling, which means we
# have to turn off this warning (and be careful about how object
# destruction happens in such cases).
