This builds the whole Boost with /EHa. You're perfectly within your rights
to do so, of course, but I'd rather not, and I don't think that this should
be the default. It makes no sense for applications that don't use
Boost.Test, for example.
(Correctness considerations aside, I suspect that this will also cause quite
a penalty in cases where the compiler can no longer remove try/catch(...)
blocks when it sees that the code inside can't throw, and those aren't
uncommon in generic code such as the implementation of std::vector.)
