Would be fantastic if you could report build time for camlboot too :). The result should be almost identical to our current ocaml-4.07, though there are some due to different output directory being embedded.

Fantastic! Thank you and thanks to the camlboot project! I will
try and
build this tonight.

Hi Guix!

This small series adds camlboot, a project to reimplement a
bootstrap
for OCaml, which lets us remove the pre-built boot/ocaml{c,lex}
:)

The first patch builds the bootstraped ocamlc and ocamllex. This
takes
around 4 hours to build. The second patch rebuilds them using
the source
code for ocaml 4.07.1, instead of the modified sources used in
camlboot, and reuse them to run the main Makefile (make
world.opt).

As a result, we have identical files for this bootstrap and the
unbootstrapped OCaml (up to output store paths and hash of some
files
that get embedded in native files, which differ because of the
different output path).
