Log Message:
guile22: update to 2.2.7.

Changes in 2.2.7 (since 2.2.6)

* New interfaces and functionality

** (texinfo plain-text) now exports '*line-width*' fluid

The new '*line-width*' fluid allows users to specify the width of a line
for the purposes of line wrapping.  See "texinfo plain-text" in the
manual.

* Bug fixes

** Reduce GC pressure when using bignums

Guile no longer installs a finalizer on each bignum (large integer) it
creates.  This significantly improves speed and memory usage on
applications that make heavy use of bignums, such as the compiler
itself.

** Fix peval bug that ignored excess arguments

In an expression like:

  ((lambda ()
     (define (add1 n)(+ 1 n))
     (add1 1 2)))

the compiler (specifically 'peval') would silently ignore the excess
argument to 'add1'.

** Respect thread local fluid defaults

Previously (fluid-ref (make-thread-local-fluid #t)) would return #f.
This is now fixed.

** Fix non-deterministic crash in 'finalization_thread_proc'
   (<https://bugs.gnu.org/37757>)

** texinfo properly renders @acronym in plain text
   (<https://bugs.gnu.org/37846>)

** 'scm_port_poll' honors "w" flags
   (<https://bugs.gnu.org/36709>)

** Do not record LDFLAGS in .pc file
   (<https://bugs.gnu.org/36339>)

** Fix Readline configure check for the sake of libedit

This fixes builds on macOS against the system-provided libedit.

** Fix build on platforms where the stack grows upwards
