You’re right. So for 2.0.10, just revert, and then remove #include
<config.h> altogether in c-tokenize.lex with a comment saying why.
Could you do that?

Yes, we had that, but I removed it in
<http://git.sv.gnu.org/cgit/hydra-recipes.git/commit/?id=aea7182a62f8c6f7a04a7e89fbdd59155d5f34ff>
because the MinGW cross toolchain in Nixpkgs had bitrot. :-/
(BTW, we can test cross-compilation to GNU/Linux with
guix build guile --with-source=guile-2.0.9.xyz.tar.xz
--target=mips64el-linux-gnu.)
