+
+Radey Shouman has changed LETREC to behave like LETREC*:
+
+ * 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

+ now HEAP_SEG_SIZE.
+
+2006-05-21 Aubrey Jaffer <agj@alum.mit.edu>
+
+ * sys.c (igc): Moved FLUSH_REGISTER_WINDOWS to after setjump().
+
+ * repl.c (scm_read_numbered): Don't #ifndef MEMOIZED_LOCALS.
+
+ * build.scm (dont-memoize-locals): Added feature.
