	* repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.

	* error.c: scm_warn eliminated.

	* error.c (scm_everr): 
	* gc.c (fixconfig):

	because it changes size.

	(stputc stwrite): check/change the strings length with interrupts
	blocked.

	* objprop.c (scm_set_object_property_x &c): use the generic
	hashing functions and be threadsafe.

	functions.  hash, hashq, hashv, hashx.

Mon Feb 19 09:38:05 1996  Tom Lord  <lord@beehive>

	* symbols.c: made the basic symbol table operations atomic.

	initialization to fix a race condition.

	* continuations.c (scm_dynthrow): pass throwval in the 'regs'
	object, not in a global.
	(suggested by green@cygnus, jaffer@gnu.ai.mit.edu)

	* throw.c (_scm_throw): Pass throwval on the stack, not in a global
	(suggested by green@cygnus, jaffer@gnu.ai.mit.edu)

	set the multi_byte flag correctly in symbols.  This is wrong.
	intern_obbary_soft and msymbolize should take an extra parameter.
	Also, weird multibyte symbols don't print correctly.
	The weird symbol syntax is also a bit bogus (emacs doesn't quite
	cope).

Tue Feb 13 11:39:37 1996  Tom Lord  <lord@beehive>

	* symbols.c (scm_string_to_obarray_symbol): obarray == #f means
