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
very large and very small complex numbers (1e300; 1e-300);
