On some platforms the compiler complains about __try and __catch not

Yes, that's right. OK for trunk, thanks.
By the way, I'm intending to add __throw_bad_variant_access_fmt to
bits/functexcept.h and make it use __snprintf_lite() so that we can
do:
__throw_bad_variant_access_fmt("cannot access alternative %zu "
"of std::variant because index() is %zu", _Np, __v.index());
(Thanks to Nico Josuttis for the suggestion).
