+scm5e4 news:
 
-Richard Harke ported SCM to the Linux-ia64.
+* Jerry van Dijk wrote NSIS script to create MS-Windows installers.
 
-SRFI-94 Type-Restricted Numerical Functions.
+* Added (compiled) byte-number module.
 
-SRFI-63 uniform array type support expanded to:
+* scm-file-position replaces file-position and file-set-position!;
+  moved from i/o-extensions module to SCM core functionality.

-Radey Shouman has changed LETREC to behave like LETREC*:
+* Added (R6RS) bitwise-bit-count.
 
-  * eval.c (ceval_1): Change LETREC behavior to that of LETREC*:
-  initializers are run in left to right order, and may use
-  previously evaluated variables bound in the same contour.  This
-  change also applies to LETRECs resulting from internal DEFINE.
-
-  * eval.c (macroexp1): Add #ifdef to switch case handling line numbers
-  in ceval_1 so that they are safely discarded when MEMOIZE_LOCALS is
-  not #defined.  Perhaps line number generation should be disabled in
-  that case.
-
-  * scl.c: Changes to allow compilation with MinGW (gnu-win32);
-  asinh, acosh, and atanh are not yet supported.
-
-From Aubrey Jaffer:
-
-  * indexes.texi (Indexes): Give each index its own node when not in
-  info mode.  Moved index stuff here so it doesn't break
-  texinfo-every-node-update.
-
-  * scm.texi (Index): Replaced nodes under Indexes with node Index
-  when in info mode; fixes indexing in Emacs 21.4.1.
-  Converted to use @copying.
-  (Indexes): Reorganized.
-  (Data Type Representations): Corrected pattern for specfun and cclo.
-
-  * byte.c (subbytes): Added.
-  (scm_subbytes_read, scm_subbytes_write): Renamed from substring.
-
-  * Makefile (dscm4, dscm5): != is string operator in shell.
-  "mv -f" for previous scm, slibcat, and implcat.
-
-  * Init5e2.scm (boot-tail): Don't load ScmInit.scm if *script*.
-  (string-index, read-line): Defined for login->home-directory, which
-  may be called before REQUIRE is defined.
-
-  * Makefile (dscm4, dscm5): Added randomize_va_space machinations.
-  (dvi, pdf): New tetex-3.0(-20.FC5) broke them -- fixed.
-  (SETARCH): Workarounds allow dumping in recent Linux.
-
-  * time.c (linux): defined CLKTCK to (sysconf(_SC_CLK_TCK)).
-
-  * repl.c (scm_read_numbered): Don't #ifndef MEMOIZED_LOCALS.
-
-  * build.scm (dont-memoize-locals): Added feature.
-  (stack-limit): Removed feature.
-
-  * scmfig.h (STACK_LIMIT): Always defined.
-  (CHECK_STACK): Condition on scm_verbose.
-
-  * sys.c (stack_check): Always present.
-
-  * Makefile (docs): Added target to make all documentation files;
-  then invoke xdvi.
-
-  * ugsetjmp.s (_setjump, _longjump): For Ultrix VAX circa 1997.
-
-  * subr.c (mkbig, adjbig): Improved overflow message.
-
-  * mkimpcat.scm (wbtab, rwb-isam): moved to "Simple associations".
-  (add-source): Use 'source form and check file's existence.
-
-  * scl.c (scm_magnitude): Extend dynamic range by eliminating
-  intermediate expression swell.
-  (divide): Use "Smith's formula" to extend dynamic range;
-  but makes an insignificant difference when compiled with -O3.
-  (atanh, acosh, asinh): define if #ifndef HAVE_ATANH.
-
-  * scmfig.h (HAVE_ATANH): Decides whether atanh, asinh, and acosh
-  are supported.
-
-  * r4rstest.scm (5 2 1): Expose Bigloo tprint redefinition bug.
-  (test-bignum): Convert test bignums from strings.
-  (have-bignums?): Check bignum arithmetic works.
-  (test-inexact): Do complex tests only if non-real numbers are
-  supported.
-  (test-inexact): Added equal? tests.
-  (test-inexact): Test for -0.0 lossage.
-  (test-inexact): Check that / and magnitude work for
-  very large and very small complex numbers (1e300; 1e-300);
+* Makefile (install*): Added $(DESTDIR) prefix.
