Hi Jonathan,

I've checked and double-checked this, and was hoping you could offer some
insight:

I get the "Undefined symbol: vtable for std::ctype<char>" error only when
bootstrapping. If I build 4.7.0 with a previously-built C-only 4.7.0 +
--disable-bootstrap, everything else the same, the build completes
successfully.

Can you make anything of that?
