# 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

# on the passed-in pointer (until later), and annotating every legit
# usage of this is simply more hassle than the warning is worth.

# C4503: 'identifier': decorated name length exceeded, name was

# This warning is unavoidable when using e.g. setjmp/longjmp. MSDN
