Hi Jan!

Jan Nieuwenhuizen <janneke@gnu.org> skribis:

> Mes 0.6 for Guix.  Nyacc is now unbundled.  Mescc works with vanilla
> Nyacc.  Mescc behaves more like a regular C compiler and now passes
> 33/55 tests of the tinycc test2 test suite.

Woow, really impressive progress.

> Mescc can also be used as a Nyacc C compiler backend for Guile (x86 only).

I got stuck in a meta-circular attempt to understand the meaning of this
sentence.  What does this mean in very explicit terms?  :-)

> +                   (equal? (%current-target-system) "x86_64-linux"))

Note that %current-system is a =E2=80=9Csystem type=E2=80=9D like =E2=80=9C=
x86_64-linux=E2=80=9D
whereas %current-target-system is a GNU triplet like
=E2=80=9Cx86_64-linux-pc-gnu=E2=80=9D.  Thus, the second line should be

  (string-prefix? (%current-target-system) "x86_64-linux")

OK with this change!
