bug#26926: [PATCH] gnu: update Mes to 0.6.

[Jan Nieuwenhuizen <janneke@gnu.org>]

[-- Attachment #1: Type: text/plain, Size: 283 bytes --]

Hi!

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.

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

Greetings,
janneke
