I think it would be fine to add the minimum infrastructure needed for
that and then just disable the WCDH and Tests/* pieces that don't work
with it.  We could also just not document this support.  Until more
people are interested in it that have time to implement it fully, I don't
think we need to fully support it beyond your use case.

I'm hesitant to switch to long_long_type because that is often supported
by compilers in C++98 mode, so it may defeat the test.

Thanks,
