 SCM4e4 release

This message announces the availability of Scheme release scm4e4.

New in scm4e4 are:

   In addition to fixing assorted bugs, I have improved the
   documentation of BUILD options and features.  Scm4e4's "build.scm"
   requires new functions from the most recent SLIB.
                                -=-=-

   Patrick LECOANET has ported Gnu Emacs' unexec to SCM.  You can load
   Scheme code for a program, save that executable, then startup the
   saved program much more quickly.  Startup time is improved by more
   than a factor of 3 under Linux:

      bash$ time -p scm -e"()"
      real 0.43
      user 0.34
      sys 0.08

      bash$ time -p dumped-scm -e"()"
      real 0.16
      user 0.04
      sys 0.09

   Startup time for large saved Scheme programs is similarly reduced
   compared to the time to load these programs.  Using DLD under
   Linux, dynamically linked (object) files can be linked both before
   and after dumping.
                                -=-=-

   Radey Shouman has made many improvents in the area of
   uniform-vectors and arrays.  Feature 'array-for-each is now
   dynamically linkable.
                                -=-=-

Scm conforms to Revised^4 Report on the Algorithmic Language Scheme
and the IEEE P1178 specification.  Scm is written in C and runs under
Amiga, Atari-ST, MacOS, MS-DOS, OS/2, NOS/VE, Unicos, VMS, Unix and
similar systems.  ASCII and EBCDIC are supported.

Documentation is included explaining the many Scheme Language
extensions in scm, the internal representations, and how to extend or
include SCM in other programs.  Documentation is online at:
