+This message announces the availability of Scheme release scm4e6.
+
+New in scm4e6 are:
+
+ * bench.scm (benchmark): added. computes and display statistics
+ on "pi.scm" benchmark.
+ * Makefile (benchlit bench): targets added. Append stats to file
+ "BenchLog".
+ * scm.texi (Socket): added examples of chat servers and clients.
+ (Internet Addresses and Socket Names): enlarged from "Internet
+ Addresses".
+ * socket.c (l_connect): BUF0 was missing from mode bits set in
+ returned port.
+ * build.scm (build-params): Added compiler-options and
+ linker-options; added --batch-dialect and --script-name as aliases
+ for -h and -w.
+ * scmfig.h (HAVE_SELECT): Now defined for linux.
+ * sys.c (igc): fixed off-by-1 error for sizeof save_regs_gc_mark.
+ (gc_mark): fixed off-by-1 error for sizeof(CONTINUATION). These
+ seem to fix a very obscure GC bug.
+ * Init.scm (exec-self): Added.
+ * repl.c (init_repl): DUMP sets RESTART to EXEC-SELF.
+ * repl.c (tryload): Made tail-recursive so that dump, quit, exit,
+ etc. will work as the last expression in a loading file.
+ (scm_execpath): Split out from scm_unexec.
+ * unexec.c: All Updated from emacs-19.34 -- no changes necessary.
+ * gmalloc.c:
+ * pre-crt0.c:
+ * ecrt0.c:
+ * unexelf.c: fixes Linux (ELF) dump bug.
+ * build.scm (platform): linux renamed linux-aout. linux-elf fixed
+ and renamed linux.
+ (C-libraries): X11R6 moved library files on RedHat Linux. Linux
+ graphics library now has entry (doesn't default).
+ (compile-dll-c-files linux):
+ (make-dll-archive linux): Now converts from ".o" objects to ELF
+ ".so" form and "links" the usual libraries.
+ * Link.scm (usr:lib x:lib): dynamic linking fixed for (linux ELF)
+ dlopen. Libraries other than ".so" object not needed; eliminated
+ by usr:lib and x:lib returning #f.
+ * dynl.c (l_dyn_unlink): prints result of dlerror() on errors.
+ * eval.c (nconc2last): If CAUTIOUS is defined, checks that
+ APPLY's arglist and last element of arglist are LIST?s.
+ * sys.c (igc): symhash GC can now be disabled with
+ #define NO_SYM_GC.
+ * Init.scm (boot-tail): Added FSF --help and --version options.
+ Added --no-init-file as a synonym for -no-init-file.
+ * scm.texi (File-System Habitat): improved wording and added
+ examples.
+ * scm.texi (Top): Renamed sections.
+ * sys.c (mark_syms mark_sym_values): Split up mark_symhash() to
+ immunize against accidental pointers.
+ * repl.c (gc_ports_collected): added to instrument symbol GC.
+ * scm.texi (Debugging Scheme Code): Added section.
+ * eval.c (definedp): Changed from a memoizing macro to a `syntax'.
+
+ From maximum entropy <entropy@zippy.bernstein.com>:
+
+ * ioext.c, scmfig.h: support for SGI (tested with SGI IRIX 5.2/gcc)
+ * ioext.c (file_set_position): If a port is bidirectional
+ (e.g. a socket) it may be necessary on some systems to perform a
+ file positioning operation when switching between reading and
+ writing. This is required by ANSI C (ISO/IEC 9899:1990
+ 7.9.5.3). Therefore, a file-set-position on a bidirectional
+ port should not signal an error if fseek generates an
+ ESPIPE -- the fseek operation actually "succeeded" in that it
+ reset the I/O direction flag for the FILE.
+ * repl.c (input_waiting): R4RS requires that "char-ready?"
+ return "#t" at end-of-file. The semantics for "ioctl(...,
+ FIONREAD, ...)" are such that it gives 0 on a socket that is
+ closed (on the other side of the connection). If the
+ system has select(), use that instead to get the correct
+ behavior.
+ * socket.c (l_listen): Treat sockets that have been "listened"
+ as input-ports. This allows polling for new connections
+ (e.g. with "char-ready?") instead of blocking in
+ "socket:accept".
+ * socket.c (l_accept): Fix type checking to agree with
+ previous patch.
+
+ From Radey Shouman <shouman@zianet.com>
+
+ * eval.c (unmemocar): The code in unmemocar to deal with ILOCs was
+ never being executed.
+ * sys.c (intern): fixed (new) symhash GC bug.
+ * sys.c (igc): Added calls to mark_symhash() and sweep_symhash().
+ These GC unused symbols with a top-level value of UNDEFINED.
+ (mark_symhash): added.
+ (sweep_symhash): added.
+
+ From Eric Hanchrow <erich@MICROSOFT.com>
+
+ * scm.c (l_sleep): Ported to Windows NT (_WIN32)
+ * ioext.c: Ported to Windows NT (_WIN32)
