# some warnings we don't like:
# c4355
# 'this' : used in base member initializer list
# The this pointer is valid only within nonstatic member functions. It cannot be used in the initializer list for a base class.
# c4800
# 'type' : forcing value to bool 'true' or 'false' (performance warning)
# This warning is generated when a value that is not bool is assigned or coerced into type bool.
# c4267
# 'var' : conversion from 'size_t' to 'type', possible loss of data
# When compiling with /Wp64, or when compiling on a 64-bit operating system, type is 32 bits but size_t is 64 bits when compiling for 64-bit targets. To fix this warning, use size_t instead of a type.
# c4244
# 'conversion' conversion from 'type1' to 'type2', possible loss of data
# An integer type is converted to a smaller integer type.
# c4290
# C++ exception specification ignored except to indicate a function is not __declspec(nothrow
# A function is declared using exception specification, which Visual C++ accepts but does not
# implement
# c4068
# unknown pragma -- added so that we can specify unknown pragmas for other compilers
# c4351
# on extremely old versions of MSVC (pre 2k5), default constructing an array member in a
# constructor's initialization list would not zero the array members "in some cases".
# since we don't target MSVC versions that old, this warning is safe to ignore.
