The result should be almost =
identical to our current ocaml-4=2E07, 
though there are some due to dif=
ferent output directory being 
embedded=2E

Checked s= ome random files in both ocaml's with diffoscope and can
confirm that d= ifferences seem to be mostly different output
directories=2E

Hav= en't run diffoscope on everything as that would take quite some
time=2E= =2E=2E

Fantastic= ! Thank you and thanks to the camlboot project! I will
try and
build = this tonight=2E

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=2E <= br> This
takes
around 4 hours to build=2E The second patch rebuilds= them using
the source
code for ocaml 4=2E07=2E1, instead of the mo= dified sources used in
camlboot, and reuse them to run the main Makefil= e (make
world=2Eopt)=2E

As a result, we have identical files fo= r 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)=2E
