Possibly: yes.

I have added tinycc-boot including tests.  I mean to refactor the
builders and just for fun add gcc-4.7.4 to this picture (see attached).

It's pretty exciting for me that I'm able to show a dependency diagram
generated by Guix of packages that build, that shows a compiler (tinycc)
that only depends on some much smaller seeds.

If you fetch branch wip-bootstrap from*) https://gitlab.com/janneke/guix
and run

    ./pre-inst-env guix graph --type=bag-with-origins tcc-boot > bag+origins.dot

you get a clear understanding of what Ricardo was saying: you'll find
the nice and clean attached image tucked away in the top right corner,
above an enormous cloud of dependencies...ugh!

Is there a way to use replace the guile-2.2.2 dependency with the static
bootstrap tarball guile-2.0.9?  That would already help a lot!

*) should i push this to savannah wip-bootstrap?
