# Do we really need to disable to many warnings? It seems to me that
# many of these warnings are for custructs that we have been actively
# cleaning away from the code, to avoid warnings when building with
# gcc or Clang and -Wall -Werror.

# C4127: conditional expression is constant

# C4189: 'identifier' : local variable is initialized but not referenced

# C4242: 'identifier' : conversion from 'type1' to 'type2', possible
#   loss of data

# C4244: nonstandard extension used : formal parameter 'identifier'
#   was previously defined as a type

# C4245: 'conversion' : conversion from 'type1' to 'type2',
#   signed/unsigned mismatch

# C4250: 'class1' : inherits 'class2::member' via dominance

# C4251: 'identifier' : class 'type' needs to have dll-interface to be
#   used by clients of class 'type2'

# C4267: conversion from 'size_t' to 'type', possible loss of data

# C4275: non-DLL-interface classkey 'identifier' used as base for
#   DLL-interface classkey 'identifier'

# C4290: C++ exception specification ignored except to indicate a
#   function is not __declspec(nothrow)

# C4351: new behavior: elements of array 'array' will be default
#   initialized

# C4355: 'this' : used in base member initializer list

# C4373: '%$S': virtual function overrides '%$pS', previous versions
#   of the compiler did not override when parameters only differed by
#   const/volatile qualifiers.

# C4481: nonstandard extension used: override specifier 'override'
# (MSVC 2010 warns about this, even though it's C++11 keyword)

# C4505: 'function' : unreferenced local function has been removed

# C4512: 'class' : assignment operator could not be generated

# C4611: interaction between 'function' and C++ object destruction is
#   non-portable

# C4626: 'derived class' : assignment operator could not be generated
#   because a base class assignment operator is inaccessible

# C4702: unreachable code

# C4706: assignment within conditional expression

# C4800: 'type' : forcing value to bool 'true' or 'false' (performance
#   warning)

# C4913: user defined binary operator ',' exists but no overload could
#    convert all operands, default built-in binary operator ',' used

# C4996: 'function': was declared deprecated
#   Also generated for C++ library functions that "may be unsafe"
