Bug 1257040 - Disable C4577 to unblock compilation on VS2015; r?jorendorff
As part of unblocking building with VS2015u1 in automation, I'm mass
disabling compiler warnings that are turned into errors. This is not
the preferred mechanism to fix compilation warnings. So hopefully
this patch never lands because someone insists of fixing the underlying
problem instead. But if it does land, hopefully the workaround is
only temporary. That being said, the warnings this patch masks are
in an included ICU header, which is a 3rd party project. So our hands
appear tied.
