# khuey says we can safely ignore MSVC warning C4251
# MSVC warning C4244 (implicit type conversion may lose data) warns
# and requires workarounds for perfectly valid code. Also, GCC/clang
# don't warn about it by default. So for consistency/sanity, we turn
# it off on MSVC, too.
# MSVC warning C4267 warns for narrowing type conversions from size_t
# to 32-bit integer types on 64-bit platforms. Since this is virtually
# the same thing as C4244, we disable C4267, too.
# MSVC warning C4800 warns when a value is implicitly cast to bool,
# because this also forces narrowing to a single byte, which can be a
# perf hit. But this matters so little in practice (and often we want
# that behavior) that it's better to turn it off.
# MSVC warning C4595 warns non-member operator new or delete functions
# may not be declared inline, as of VS2015 Update 2.
