This message announces the availability of Scheme release scm5e1.
New in scm5e1:
* r4rstest.scm: Removed tests for 0^0 in anticipation of SRFI-70.
* r4rstest.scm (test-numeric-predicates): Raised exponent so
intransitive 128-bit-float implementations are caught.
* r4rstest.scm (SECTION 6 5 5): Removed tests for (EXPT 0 -255)
so Common-Lisp compatible EXPT won't bomb.
Test EXPT inexactness contagion of zero cases.
* r4rstest.scm (SECTION 6 5 5): Added exact tests for EXPT.
Inexact EXPT corner cases should return inexacts.
* r4rstest.scm: Added URLs.
* Transcen.scm (limit): Check and report input errors.
* Transcen.scm (limit): Added srfi-70 procedure.
* Transcen.scm (expt, quotient, remainder, modulo): SRFI-70 extensions.
* Transcen.scm (expt): Changed so (expt 0 -5) signals error.
EXPT of zero returns zero or one matching input exactness.
* Link.scm (link:link): Converted to use with-load-pathname.
* Init5d9.scm (numerator, denominator): Check rational.
* Init5d9.scm (numerator, denominator): Added.
* Init5d9.scm (with-load-pathname): Moved from slib/require.scm.
* Init5d9.scm (any-bits-set?, first-set-bit, bitwise-merge): Added
remaining SRFI-33 aliases.
* Init5d9.scm (read-array-type): Handle A:char.
* Init5d9.scm (list->array, vector->array, array->vector): Added.
* Init5d9.scm: Updated per SRFI-60.
* Init5d9.scm (arithmetic-shift): Aliases ASH.
* Init5d9.scm (read:array, read:sharp): Accept whole boatload of
SRFI-58 sytnaxes.
* Init5d9.scm (inexact->exact, exact->inexact): Identity when
exacts-only.
* Init5d9.scm (slib:eval-load): Converted to use (SLIB)
with-load-pathname.
* Init5d9.scm (slib:eval-load): Define moved to "slib/require.scm"
* Init5d9.scm (read:array): Ignore third argument; line-numbers
were hosing array reading.
* build.scm (dlll gnu-win32): Changed flag to "-DSCM_WIN_DLL".
(dlll microsoft-c-nt): Changed flag to "-DSCM_WIN_DLL".
* build.scm (wb): Added for source in ../wb/.
(build:command): Assume c-files are relative to cd; don't prefix
c-files with scm-srcdir.
(compile-dll-c-files): Many were missing include-spec "-I" call.
* build.scm (compile-dll-c-files): For those platforms supporting
shared object files, generate just one combining all FILES.
* build.scm (compile-dll-c-files): Fixed -I for netbsd, openbsd.
(compile-dll-c-files): Added -I for svr4-gcc-sun-ld.
(file-categories): Renamed CORE from REQUIRED.
* mkimpcat.scm: Support WB compiled in implementation-vicinity.
* mkimpcat.scm: Added 'DIFF.
* xgen.scm, build.bat, inc2scm: Replaced %0 ... %9 with %~f0 %*
* scmhob.scm: Moved LOGICAL: aliases from logical.scm.
* Makefile (install): Added db.so.
(uninstall): Beefed up.
* Makfile (scm5): Added target for undumpable architectures (FC3).
* Makefile (SETARCH): Workaround for unexec on Fedora Linux i386.
* Makefile (mydlls): Call BUILD separately for each dll.
* Makefile (srcdir.mk): Include after target.
Separated shell assignments and exports.
* Makefile: (SHOBJS): Abstracted *.sl and *.so.
* Makefile (db.so, rwb-isam.scm, wbtab.scm): Added.
* Makefile (differ.so): Added target.
* scm.spec (differ.so, Idiffer.scm): Added to %files.
* scm.texi (MS-DOS Compatible Scripts): Replaced %0 ... %9 with %~f0 %*
* scm.texi (SCMDB): Added section with link.
(Hobbit): Moved notinfo stuff after Xlib so it appears same place
in all products.
* scm.texi (Sequence Comparison): Added.
* scm.texi (SIOD copyright): Put in subsection.
(The SCM License): Parallel Guile License text.
* scm.texi (Automatic C Preprocessor Definitions): Added "sun".
* scm.h (infi): Nonreal infinity added to sys_protects.

* scl.c (scm_intexpt): Bombed given (integer-expt 0 25).
* subr.c (scm_copybitfield): Changed argument order (SRFI-60).
* unif.c (scm_prot2type): Was not defaulting correctly.
* unif.c (raprin1): Don't elide 1 from #1A.
* unif.c, sys.c: Sun cc doesn't like fwrite declaration.
* byte.c (scm_write_byte): Was hosed for even number of bytes.
* byte.c (scm_substring_read): Fixed off-by-one reading backwards.
* ramap.c (array:copy!): Renamed from array-copy!.
(array_copy): Arguments reversed.
* ramap.c (init_ramap): Its tc7_subr_2 not tc7_subr2!
* ramap.c (rafe): Removed unused variables inc and base.
* repl.c (err_head): Fixed "loaded from" messages and formatting.
* repl.c (iprin1): Slashify uppercase chars in symbols.
* repl.c (read_token, iprin1, lreadr): Handle slashified symbols.
* repl.c (handle_it): Added comments. Call scm_fill_freelist() if
interrupt lacks handler.
* repl.c (scm_top_level): Default value of toplvl_fun just once.
* differ.c, Idiffer.scm: Linear-space O(PN) sequence comparison.
* eval.c (definedp): Added third (dummy) argument.
From Radey Shouman:
* Init5d9.scm (read:array): Make default rank one, not zero.
(as before).
* Init5d9.scm (read:array): (read:sharp): (load:sharp): Use read
argument passed to READ:SHARP only for eval, otherwise unexpected
line numbers cause trouble. eg #+(or) in load file.
* script.c (find_impl_file): Find executable path accurately
on MS windows.
* scm.texi (Debugging Continuations): Added documenting
frame-trace, frame->environment, scope-trace, frame-eval.
* eval.c (toplevel_define) (scm_arity_check) (ceval_1)
(scm_cvapply) (apply): Pass multiple arguments to captured
continuations, eg:
(call-with-values (lambda () (call/cc (lambda (k) 1 2))) list)
Better error checking for multiple-value returns in repl.
* sys.c (scm_dynthrow): Allow passing multiple arguments
to a continuation captured in the producer argument of
call-with-values.
* subr.c (scm_logbitp): Fixed bug in range check for fixnum
case. Eg (logbit? 10 #xffff) now correctly returns #t.
* eval.c (macroexp1): Catch more syntax errors: ('f . f)
* eval.c (m_case) (definedp): Avoid segfault in cases of syntax
error.
From Wim Lewis:
* Makefile (scmflags): Use "cmp -s" instead of "diff".
(x.h): Use -x $CPROTO to test for cproto's existence.
