-This message announces the availability of Scheme release scm5d2.
-
-New in scm5d2:
-
-	* Makefile (install): Make sure $(libscmdir)require.scm exists.
-	(libscmdir): Use instead of IMPLPATH.
-	* repl.c (scm_top_level): Corrected error test on exit in case 0
-	is not success.
-	(repl): Return MAKINUM(EXIT_SUCCESS) when exiting an interactive
-	session on EOF, this should not be an error.
-	* build.scm (define-compile-commands): Added.
-	(defcommand): Added.
-	(platform): formatted; simplified names.
-	* Makefile (features.txi): Added.
-	* scm.texi (Build Options): take feature documentation from
-	"features.txi".
-	* build (make-features-txi): Creates documentation of build
-	features from 'features table.
-	* build.scm (build:define-feature): Added.  Feature definitions
-	moved to top level.
-	* Init5d1.scm (comment): Added.
-	(read:sharp): Added `#;' comment syntax, *feature* SHARP:SEMI.
-	* sys.c (scm_env_v2lst): Made tolerant to argc of zero,
-	since ecache_evalx may call it thus for DO loops binding
-	no values.
-	* eval.c (debug_env_save): Function for use in ENV_SAVE when the
-	CAREFUL_INTS paranoid debugging flag is #defined.
-	(ecache_eval_args): Now calls ecache_evalx(), which
-	evaluates a list of expressions and returns a list allocated on
-	the ecache in scm_env_tmp.
-	(m_do): (m_letrec1): (ceval_1): LET, LETREC, and DO now call
-	ecache_evalx instead of using inline loops, this seems to improve
-	speed by 5% - 10% for jacal and for simsynch simulation.  C stack
-	usage will increase somewhat for large env frames.
-	(lookupcar): Added support for constant bindings, to be created by
-	LET, LETREC, LET*.
-	* scl.c (dbl_prec): Use dbl_mant_dig in preference of potentially
-	undefined DBL_MANT_DIG.
-	* gmalloc.c: include "getpagesize.h" conditionalized on __svr4__.
-	* build.scm (batch:chop-to-fit-system): Removed.  Use new
-	batch:try-chopped-command instead.
-	(mysql): Added to features.
-	(build:build): Added comments describing stages and errors.
-	* Makefile: Added platform.txi dependency where dependent on
-	scm.texi.
-	* Makefile (scm.info require.scm): "cp -p" more portable than "cp -a"?
-	* sys.c (mode_bits): Fix for null output string case.
-	* unif.c (make_sh_array): Reduced consing by using scm_cvapply
-	instead of apply.
-	*sys.c (mode_bits): Now takes an optional buffer which, on exit,
-	will hold a mode string suitable to pass to fopen(), without any
-	SCM extension characters.
-	* r4rstest.scm (float-print-test): stop after first error.
-	* sys.c (try_open_file): Insure that only 'r', 'w', 'b', or '+'
-	may be included in mode strings passed to fopen.
-	* repl.c (scm_freshline): Added FRESHLINE.
-	* sys.c (init_storage): Make def_outp tracked, so freshline will
-	work with it.
-	* ramap.c (cind): Now takes C vector of indices, which may be
-	allocated on the C stack, rather than a uve.
-	(ramapc): (ramap): (ramap_cxr): (array_imap): (array_for_each): (rafe):
-	Use scm_cvapply instead of apply, allocate index and argument vectors
-	on the C stack for array ranks < 5.
-	* record.c (makrectyp): (recprin1): Use scm_cvapply instead of
-	apply.
-	(rec_prinset): Checks arity of argument procedure.
-	* sys.c (sfputc): (sfwrite): (sfgetc): Use scm_cvapply instead of
-	apply.
-	(mksfpt): Checks arities of soft port procedures when the port is made.
-	* eval.c (scm_cvapply): (scm_arity_check): Exported.
-	(makacro): (makmacro): (makmmacro): Call scm_cvapply rather than
-	consing up argument lists.  Check arity of macro transformers
-	once, when syntax is defined.
-	* subr.c (make_vector): Fixed broken length argument test.
-	* sys.c (scm_env_v2lst): Now takes list tail in scm_env_tmp, so
-	tail can be allocated on ecache.
-	* repl.c (scm_top_level): Print out supplied program arguments for
-	failure exits to simplify debugging scripts.
-	* eval.c (varcheck): Fixed for RECKLESS case.
-	* eval.c (scm_arity_check): (macroexp1): Argument number checking
-	in macroexp1 abstracted as scm_arity_check, for use in map,
-	for-each ...
-	(scm_cvapply):  Apply a function to a C vector of arguments, used by
-	map and for-each.
-	(scm_v2lst):  Added for use in scm_cvapply.
-	(map): (for_each): Speed considerably improved: No longer allocate
-	Scheme vector temporaries for up to 5 list arguments.  No longer
-	allocate unnecessary argument lists, allocate on ecache if
-	possible.
-	* repl.c (iprin1): Print out first elt of cclo environment --
-	makes record procedures more identifiable.
-	* sys.c (scm_env_v2lst): Now takes last cdr of list as argument.
-	* sys.c (scm_port_entry): Make 16-bit safe.
-	* Tscript.scm: File added to implement transcript-on,
-	transcript-off without burdening normal i/o.
-	* Init5d1.scm (transcript-on): (transcript-off): Now autoloads
-	from SCM/Tscript.scm
-	(_TRACKED): Added.
-	* socket.c (l_socket): (l_connect): (l_listen): Modified to use
-	port table.
-	(l_shutdown): (l_getpeername): (l_getsockname): Test for OPFPORTP, not
-	just OPPORTP.
-	* posix.c (l_pipe): Modified to use port table.
-	(prinpipe): Removed.
-	* ioext.c (reopen_file): (l_dup): (l_dup2): Modified to use port
-	table.
-	* crs.c (prinwindow): Removed.
-	(mkwindow): Uses scm_port_entry.
-	* repl.c (iprin1): Uses "name" field for printing ports.
-	(input_waiting):  (wait_for_input):
-	(trans_on): (trans_off): Removed in favor of soft-port implementation.
-	(lputc): (lgetc): (lputs): (lfwrite): (lungetc): Removed check for
-	transcript, added line and column number support.  Unread char now
-	kept in port table rather than CAR.
-	(lreadpr): (line_num): Removed line counting for load port, now done
-	using general line and column counting.
-	(scm_port_line): (scm_port_column): (scm_port_filename): Added.
-	(err_head): Now prints out multiple filenames for nested loads.
-	Tries to recover from recursive errors if current-error-port is a
-	soft-port.
-	* unif.c (uve_read): Removed ungetc call, if there is an unread
-	character, just call lgetc repeatedly for the first elt.
-	* sys.c (must_malloc): (must_realloc): Now check whether the heap
-	is initialized or not, so may be called earlier.
-	(scm_init_gra): (scm_grow_gra):  Use above feature.
-	(scm_port_entry):  Added, allocates entry in a port table used to store
-	unread characters, file names, line & column numbers, &c.
-	(mark_port_table): (sweep_port_table): Gc support for port table.
-	ptobfuns now has a "name" element, used for printing.
-	(prinfport): (prinstpt): (prinsfpt):  Removed.

- From David Yeh:
-	* scl.c (makdbl): Mods to compile using MSVC.
-	* scmfig.h: Don't #define SINGLES for MSC.

+New in scm5d6:
+
+From Aubrey Jaffer:
+
+ + Tanel Tammet's Hobbit compiler is now integrated into the SCM
+   distribution.
+
+ + hobbit.scm modified for (symbol) GC changes in SCM.  Use of
+   scm_gc_protect() instead of lists of protected objects means code
+   produced by Hobbit is smaller and more readable.
+
+ + Converted the hobbit documentation to texinfo format.
+   http://swissnet.ai.mit.edu/~jaffer/hobbit_toc.html
+
+From George Bronnikov:
+
+ + Ported SCM to the PLAN9 operating-system.
+
+From Martin Lafaix
+
+ + scm.c (l_raise, l_sleep):
+ + script.c (dld_find_executable):
+ + scmmain.c, scmfig.h: Ported to OS/2, IBM VisualAge C++ v3.
+
+Plus improvements and bug fixes too numerous to include here (see
+scm/ChangeLog).
