GNU Guile 2.2.2 released

GNU Guile 2.2.2 released

[Andy Wingo]

We sheepishly announce GNU Guile release 2.2.2, a quick bug-fix to the
recent 2.2.1 release.

This release restores our ability to compile with libgc 7.2, and
restores the ability of syntax objects to be structurally compared with
equal?.

Guile is an implementation of the Scheme programming language.

The Guile web page is located at https://gnu.org/software/guile/, and
among other things, it contains a copy of the Guile manual and pointers
to more resources.

Guile can run interactively, as a script interpreter, and as a Scheme
compiler to VM bytecode.  It is also packaged as a library so that
applications can easily incorporate a complete Scheme interpreter/VM.
An application can use Guile as an extension language, a clean and
powerful configuration language, or as multi-purpose "glue" to connect
primitives provided by the application.  It is easy to call Scheme code
From C code and vice versa.  Applications can add new functions, data
types, control structures, and even syntax to Guile, to create a
domain-specific language tailored to the task at hand.

Guile implements many common Scheme standards, including R5RS, R6RS, and
a number of SRFIs.  In addition, Guile includes its own module system,
full access to POSIX system calls, networking support, multiple threads,
dynamic linking, a foreign function call interface, and powerful string
processing.

Guile 2.2.2 can be installed in parallel with Guile 2.0.x; see
https://www.gnu.org/software/guile/manual/html_node/Parallel-Installations.html.

Changes in 2.2.2 (since 2.2.1):

* Bug fixes

** Syntax objects are once more comparable with 'equal?'

The syntax object change in 2.2.1 had the unintended effect of making
syntax objects no longer comparable with equal?.  This release restores
the previous behavior.

** Restore libgc dependency

The change to throw exceptions when mutating literal constants partly
relied on an interface that was added to our garbage collector (BDW-GC)
after its 7.2 release.  Guile 2.2.2 adds a workaround to allow Guile to
continue be used with libgc as old as 7.2.

** SRFI-37 bug fix to not error on empty-string arguments.

Thanks to Thomas Danckaert for fixing this long-standing bug.

[*] 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 guile-2.2.2.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 FF478FB264DE32EC296725A3DDC0F5358812F8F2

and rerun the 'gpg --verify' command.

This release was bootstrapped with the following tools:
  Autoconf 2.69
  Automake 1.15
  Libtool 2.4.6
  Gnulib v0.1-1157-gb03f418
  Makeinfo 6.3

Happy hacking with Guile,
