Gnus/5.13 (Gnus v5.13) Emacs/27.2 (gnu/linux)
We are thrilled to announce the release of GNU Mes 0.24, representing
222 commits over one year by four people.
Mes has now been ported to M2-Planet and can be bootstrapped using
stage0-posix, starting from the 357-byte hex0 binary of the
bootstrap-seeds, as was promised at FOSDEM'21.
We are exciteda that the NlNet Foundation is again sponsoring this
Work to integrate this so-called "Full Source Bootstrap" is happening on
the wip-full-source-bootstrap branch. Also, full Guile compatible
module support, and RICS-V support.
GNU Mes is a Scheme interpreter and C compiler for bootstrapping
the GNU System. Since version 0.22 it has again helped to halve the
size of opaque, uninspectable binary seeds that are currently being
used in the Reduced Binary Seed bootstrap of GNU Guix. The
final goal is to help create a full source bootstrap as part of the
bootstrappable builds effort for UNIX-like operating systems.
The Scheme interpreter is written in ~5,000 LOC of simple C, and the C
compiler written in Scheme and these are mutual self-hosting. Mes can
now be bootstrapped from M2-Planet and Mescc-Tools.
Mes has a Garbage Collector, a library of loadable Scheme modules--
notably Dominique Boucher's LALR, Pre-R6RS portable
syntax-case with R7RS ellipsis, Matt Wette's Nyacc --and test
suite, just enough to support a REPL and a C99 compiler: mescc.
Mes + MesCC + Mes C Library can build a bootstrappable TinyCC that
is self-hosting. Using this tcc and the Mes C library we now have a
Reduced Binary Seed bootstrap for the gnutools triplet: glibc-2.2.5,
binutils-2.20.1, gcc-2.95.3. This is enough to bootstrap Guix for
i686-linux, x86_64-linux, armhf-linux and aarch64-linux.
Mes is inspired by The Maxwell Equations of Software: LISP-1.5 --
John McCarthy page 13, GNU Guix's source/binary packaging transparency
and Jeremiah Orians's stage0 357-byte self-hosting hex assembler.

[*] Use a .sig file to verify that the corresponding file (without the

and the corresponding tarball. Then, run a command like this:
gpg --verify mes-0.24.tar.gz.sig

or that public key has expired, try the following commands to update
or refresh it, and then rerun the 'gpg --verify' command.

* Changes in 0.24 since 0.23
*** Mes and Mes C Library can now be built with M2-Planet.
*** Mes now supports the --bootstrap build on ARM.
*** MesCC now supports the integer suffixes:
Next to `U', also support `ULL', `UL', `L', and `LL'.
** Noteworthy bug fixes
*** MesCC now uses the unsigned type for sizeof.
*** MesCC now only uses signed division if numerator is signed.
*** The Mes C library now supports an argv bigger than 255.
*** Development build support with Guile-2 was resurrected.
*** The logand procedure now works correctly.
*** The 64bit build was resurrected.
