# Do we really need to disable this many warnings? It seems to me that

# gcc or Clang and -Wall -Werror.

# C4091: 'typedef ': ignored on left of '' when no variable is declared

# C4100: 'identifier' : unreferenced formal parameter

# C4127: conditional expression is constant

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

# C4200: nonstandard extension used : zero-sized array in struct/union

# C4201: nonstandard extension used : nameless struct/union

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

# 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
# (an issue with MSVC 2013 that appears to be gone with MSVC 2015)

# C4373: '%$S': virtual function overrides '%$pS', previous versions
#   of the compiler did not override when parameters only differed by
#   const/volatile qualifiers.
# [translation: ancient compilers that don't actually support C++ do
#  stupid things]

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

# C4510: 'class' : default constructor could not be generated

# C4512: 'class' : assignment operator could not be generated
# (an issue with MSVC 2013 that appears to be gone with MSVC 2015)

# C4610: 'class' can never be instantiated - user defined constructor required

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

# C4702: unreachable code

# C4706: assignment within conditional expression

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