Add mes and mescc-tools-extra

Browse source 
mescc-tools-extra contains two important tools:
- cp
- chmod

mes first builds itself from a mes 0.21 seed as used by guix, and then
builds a mes 0.22 and then mes 0.22 using that created mes 0.22.

It does /not/ use bootstrap.sh as we don't have a proper shell at this
point, it has been manually adapted for kaem.

Subject: GNU Mes 0.22 released
<#secure method=pgpmime mode=sign>
We are pleased to announce the release of GNU Mes 0.22, representing
57 commits over 8 weeks.
Mes can now be built reproducibly by mes+mescc or guile+mescc accross
distributions such as GNU Guix, Debian GNU/Linux and NixOS. Also, many
build issues were fixed. A big thank you to reproducible-builds.org,
Vagrant Cascadian, Jelle van der Waa, Hannes Mehnert and David Terry!
Mes now runs on the Hurd--mescc does not run yet, many system calls are
missing, especially fork/exec--and initial scaffolding support for
creating FreeBSD binaries was added.
This release better supports bringing the Scheme-only bootstrap to Guix:
it no longer requires an update to the Guix bootstrap seed.
The Scheme-only bootstrap means that Mes can now be built with Gash and
the experimental Gash Core Utils instead of using GNU Awk, GNU Bash, the
GNU Core Utilities, GNU Grep, GNU Gzip, GNU Make, GNU Sed, and GNU Tar.
Also, the Mes C Library now supports bootstrapping those.
We are excited that the Nlnet Foundation[12] is now sponsoring this
work!
Next targets:
- Introduce the Reduced Binaries Seed bootstrap to NixOS (Debian,
Arch, Gentoo, ...?)
- Merge the Scheme-only bootstrap, the wip-bootstrap branch (using
Guile, Gash and Gash Core Utils to remove awk, bash, core utilities,
grep, gzip, make, sed, tar, etc. from the Guix bootstrap binaries)
into Guix core-updates.
- ARM support
- Full Source Bootstrap: compile Mes.c using M2-Planet
- Add full Guile module support
- Reduced Binary Seed bootstrap for ARM
- Support mescc on the Hurd (fork/exec, ...)
Packages are available in Guix master; the cross-distro reproducible
is built using
guix build --system=i686-linux mes-rb5
* About
GNU Mes[0] 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[1] of GNU Guix[2]. The final goal is to help
create a full source bootstrap as part of the bootstrappable builds[3]
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. This
mes.c is being simplified[4] to be transpiled by M2-Planet[5].
Mes has a Garbage Collector, a library of loadable Scheme modules--
notably Dominique Boucher's LALR[6], Pre-R6RS [portable syntax-case[7]
with R7RS ellipsis, Matt Wette's Nyacc[8] --and test suite just enough
to support a REPL and a C99 compiler: MesCC.
Mes+MesCC can compile an only lightly patched TinyCC[9] 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 and x86_64-linux.
Mes is inspired by The Maxwell Equations of Software: LISP-1.5[10] -- John
McCarthy page 13, GNU Guix's source/binary packaging transparency and
Jeremiah Orians's stage0[11] ~500 byte self-hosting hex assembler.

[*] Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact. First, be sure to download both the .sig file
and the corresponding tarball. Then, run a command like this:
gpg --verify mes-0.22.tar.gz.sig
If that command fails because you don't have the required public key,
then run this command to import it:
gpg --keyserver keys.gnupg.net --recv-keys 1A858392E331EAFDB8C27FFBF3C1A0D9C1D65273
and rerun the 'gpg --verify' command.

** Core
*** Mes now builds reproducibly with MesCC, cross distribution
Using --with-bootstrap on x86, a bin/mes-mescc is compiled with
mes+mescc, that shall have sha256sum
9e0bcb1633c58e7bc415f6ea27cee7951d6b0658e13cdc147e992b31a14625fb bin/mes-mescc
This has been verified on GNU Guix, Debian GNU/Linux and NixOS.
*** Mes now builds reproducibly with Guile+MesCC vs Mes+MesCC.
*** Mes now builds reproducibly with Tiny CC-built MesCC.
*** configure now respects the user's CFLAGS, CPPFLAGS and LDFLAGS.
*** Mes now supports mescc-tools 0.5.2 next to 0.6.1.
This allows introducing the Scheme-only bootstrap without updating or
adding new bootstrap binary seeds into GNU Guix.
*** Mes now runs when configured --with-courage on the Hurd:
GNU debian 0.9 GNU-Mach 1.8+git20170609-486/Hurd-0.9 i686-AT386 GNU
Note that mescc does not run; fork and exec are not yet implemented.
*** Mes now configures --with-courage on x86-FreeBSD 12.1
The initial ELF scaffold tests: exit-42.S, 0exit-42.hex2,
body-exit-42.hex2, hello-mes.S, 0hello-mes.hex2, body-hello-mes.hex2
pass.
*** configure now has a --with-bootstrap option.
This adds the reproducible bootstrap build of bin/mes-mescc, using
mes+mescc.
*** configure prefers $CC over gcc; tcc over gcc, gcc over cc.
*** Mes now prints an error when attempting to read a file that does not exist.
*** Mes no longer depends on GIT.
** Noteworthy bug fixes
*** Several annoying build problems were fixed, for non-Guix systems.
*** A bug with buffered-read was fixed.
This means that bash-2.05 can now build glibc-2.2.5; notably it now
successfully executes make-syscall.sh.
*** A bug with execlp, execvp for file names containing a slash was fixed.
This should allow make-3.80 running scripts that have "#! ./move-if-change".
Greetings,
janneke and Danny.
