DRAFT lib: Only provide dlopen, dlclose prototype for BOOTSTRAP.

* include/dlfcn.h (dlopen, dlclose)[!BOOTSTRAP]: Remove.
DRAFT lib: Use FLT_RADIX==2. Fixes gawk-3.1.8.

 Please send Mes bug reports to bug-mes@gnu.org.

-* Changes in 0.24.2 since 0.24.1
-** Build
-*** A number of compile warnings have been fixed.
-*** The `simple.make' and `simple.sh' builds have been resurrected.
-** MesCC
-*** Some assembly defines were added for building TinyCC for x86_64.
-*** `__assert_fail' has been updated to use the standard signature.
-** Noteworthy bug fixes
-*** A bootstrap build without M2-Planet is now supported again.
-*** `gettimeofday' no longer segfaults in the M2-Planet build.
-*** `stat64' and friends are now used on 32bit platforms.
-This fixes https://debbugs.gnu.org/41264, and should also fix
-https://debbugs.gnu.org/49985,
-https://debbugs.gnu.org/53415,
-https://debbugs.gnu.org/53416.
-*** The Mes C Library now supports uppercase hex conversions.
 * Changes in 0.24.1 since 0.24
 ** Build
 *** Support M2-Planet bootstrap for ARM.

-Subject: GNU Mes 0.24.2 released
-
-<#secure method=pgpmime mode=sign>
-
-We are happy to announce the release of GNU Mes 0.24.2, representing 25
-commits over nine months by four people.
-
-This release should fix the long standing `stat64' bug #41264[0].
-
-We are very grateful that the NLnet Foundation[1] is sponsoring this
-work!
-
-What's next?
-
-Work to prototype this so-called "Full Source Bootstrap" for ARM on
-Aarch64 is happening on the wip-aarch64-bootstrap[2] branch.  Also, full
-Guile compatible module support, and RISC-V support.
-
-Enjoy!
-
-* About
-
-  GNU Mes[3] 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[4] of GNU Guix[5].  The
-  final goal is to help create a full source bootstrap as part of the
-  bootstrappable builds[6] 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[7] and Mescc-Tools[8].
-
-  Mes has a Garbage Collector, a library of loadable Scheme modules--
-  notably Dominique Boucher's LALR[9], Pre-R6RS portable
-  syntax-case[10] with R7RS ellipsis, Matt Wette's Nyacc[11] --and test
-  suite, just enough to support a REPL and a C99 compiler: mescc.
-
-  Mes + MesCC + Mes C Library can build a bootstrappable TinyCC[12] 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[13] --
-  John McCarthy page 13, GNU Guix's source/binary packaging transparency
-  and Jeremiah Orians's stage0[14] 357-byte self-hosting hex assembler.
-
-* Download
-
-  git clone git://git.savannah.gnu.org/mes.git
-
-  Here are the compressed sources and a GPG detached signature[*]:
-    https://ftp.gnu.org/gnu/mes/mes-0.24.2.tar.gz
-    https://ftp.gnu.org/gnu/mes/mes-0.24.2.tar.gz.sig
-
-  Use a mirror for higher download bandwidth:
-    https://ftpmirror.gnu.org/mes/mes-0.24.2.tar.gz
-    https://ftpmirror.gnu.org/mes/mes-0.24.2.tar.gz.sig
-
-  Here are the SHA1 and SHA256 checksums:
-
-  xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx  mes-0.24.2.tar.gz
-  xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx  mes-0.24.2.tar.gz
-
-  [*] 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-0.24.2.tar.gz.sig
-
-  If that command fails because you don't have the required public key,
-  or that public key has expired, try the following commands to update
-  or refresh it, and then rerun the 'gpg --verify' command.
-

- * Changes in 0.24.2 since 0.24.1
- ** Build
- *** A number of compile warnings have been fixed.
- *** The `simple.make' and `simple.sh' builds have been resurrected.
- ** MesCC
- *** Some assembly defines were added for building TinyCC for x86_64.
- *** `__assert_fail' has been updated to use the standard signature.
- ** Noteworthy bug fixes
- *** A bootstrap build without M2-Planet is now supported again.
- *** `gettimeofday' no longer segfaults in the M2-Planet build.
- *** `stat64' and friends are now used on 32bit platforms.
- This fixes https://debbugs.gnu.org/41264, and should also fix
- https://debbugs.gnu.org/49985,
- https://debbugs.gnu.org/53415,
- https://debbugs.gnu.org/53416.
- *** The Mes C Library now supports uppercase hex conversions.
