My eyes normally skip past any boost issues, so I haven’t really looked
at those. There’s a lot of “related” links and dependent packages, but
the only reference to boost.context is removing the patch used in 1.60.

I can’t build the example in #1559, even after removing all “strict”
options - maybe updates to gcc and mingw-w64 have some affect?

One link mentioned needing `masm` - should we look at building that?

Probably should continue discussion on github.

Cheers,
