This message announces the availability of Scheme release scm4c4.

New in scm4c4 are:
	* Init.scm scm.c scm.1: command line proccessing totally
	rewritten.  Thanks to Scott Schwartz
	<schwartz@groucho.cs.psu.edu> for his help with this.
	* config.h: moved flags to top per suggestions from Bryan
	O'Sullivan (bosullvn@serd.cscs.ch).
	* repl.c config.h (EXIT_SUCCESS EXIT_ERROR): added.  Values
	returned by SCM program.
	* sys.c (pwrite): added to stubbify fwrite to fix bug on VMS.
    From: pegelow@moorea.uni-muenster.de (Ulrich Pegelow)
	* scl.c (add1): finally a way to fool optimizing gcc to not use
	extra precision registers.
    From: Vincent Manis <manis@cs.ubc.ca>
	* sys.c (stwrite init_types add_final): fixed declarations.
