On my--because of this great merger--already bitrotten wip-bootstrap branch, I managed to build make using the earlier Gash (without bash or any bootstrap binaries except xz or bootstrap-guile). So my hope for the Scheme-only bootstrap is work up to a gash 0.1 and then build make, patch (awk?), gzip and possibly xz. At the R-B summit we have expressed the wish to create a single-binary fat bootstrap Guile, probably coming with Gash. Great possibilities ahead! > There is still a lot to do.

That's another option too. I still hope that with `make' built, gash will be able to build patch. > You can see the latest code at <https://gitlab.com/samplet/geesh> (yes, > the URL needs an update).
