In that thread, Gennadiy say it does not need that from Boost.System, that it only needs client to set that. It's not quite clear
whether Boost.Test itself should be built with that or not.

Anyway, my primary point, if you allow a bit of ranting, is that it's clearly Boost.Test that tries to use custom
settings that cause issues, but the people who appear to care most are Jürgen and Paul and you and I, neither of
whom are Boost.Test maintainers. That's not really productive. So with this change, it's up to Boost.Test maintainers to do
whatever is right, which might be updating documentation, or using just explicit /EHa cflags, or something else.
