I'm hoping it's simply a matter of sticking the right data in a
lookup table and letting the C++ runtime figure out what the
proper match is for us.

D currently has a custom mechanism for throwing on non-Windows
platforms, but it may be worth switching to the established C++
approach, provided we can do so without losing anything (and this
is a big "if" given how we implicitly chain exceptions).
