* libguile/read.c (scm_i_scan_for_encoding): Fix for coding on first
line #! and for !# immediately following the coding.
* test-suite/Makefile.am:
* test-suite/tests/coding.test: Add tests.
* module/ice-9/psyntax.scm (with-syntax): Allow definitions in the body,
as seems to be suggested by the R6RS.
* test-suite/tests/syncase.test ("with-syntax"): Add test.
* module/ice-9/psyntax-pp.scm: Regenerate.
* libguile/dynl.c (sysdep_dynl_value): Failure to find a symbol is not
an error, so raise our own, more appropriate error.
* test-suite/tests/foreign.test ("dynamic-pointer"): Add a test.
* libguile/continuations.c (scm_handler, c_handler)
(scm_c_with_continuation_barrier, scm_with_continuation_barrier):
Instead of calling scm_handle_by_message_noexit in the pre-unwind
handler, roll our own exception printing in the pre-unwind, and do to
exit()-on-quit in the post-unwind handler. This lets the stack unwind
at exit-time so that pending dynwinds run.
* test-suite/tests/continuations.test ("continuations"): Add a test.
* module/language/tree-il/compile-glil.scm (flatten): When compiling a
<prompt> in push context with an RA, after the body returns normally,
jump to that RA instead of to our POST label (which in that case does
not need to be emitted). Fixes a tail <prompt> in a push <fix>.
* test-suite/tests/control.test ("prompt in different contexts"): Add
more test cases.
* libguile/continuations.c (scm_handler, c_handler)
(scm_c_with_continuation_barrier, scm_with_continuation_barrier): Call
scm_handle_by_message_noexit in the post-unwind handler, so that
dynwinds
* test-suite/tests/continuations.test ("continuations"): Add a test.
* libguile/snarf.h: New macro `SCM_SNARF_INIT_PREFIX'. (SCM_SNARF_INIT)
Use `SCM_SNARF_INIT_PREFIX' instead of including a literal marker. If
the preprocessor echoes #define directives to its output, this will
prevent `guile-snarf' from snarfing the `SCM_SNARF_INIT' definition
itself. Reported by Mike Gran <spk121@yahoo.com>.
* libguile/guile-snarf.in (modern_snarf): Don't output anything for
lines in which only one of the magic snarfing markers is present.
Modify the `sed' program for compatibility with POSIX `sed'. The new
`sed' program is based on a version by Wolfgang Jenkner
<wjenkner@inode.at>.
* test-suite/standalone/test-guile-snarf: New tests.
* test-suite/tests/i18n.test (%german-utf8-locale, %greek-utf8-locale):
New variables.
(under-german-utf8-locale-or-unresolved,
under-greek-utf8-locale-or-unresolved): Use them.
Thanks to Mark H Weaver <mhw@netris.org> for coming up with most of the
examples.
* test-suite/tests/i18n.test (%german-utf8-locale-name,
%greek-utf8-locale-name): New variables.
(under-german-utf8-locale-or-unresolved,
under-greek-utf8-locale-or-unresolved): New procedures.
("text collation (German)", "text collation (Greek)"): New tests
prefixes.
("string mapping")["string-locale-upcase German",
"string-locale-upcase Greek", "string-locale-upcase Greek (two
sigmas)", "string-locale-downcase Greek", "string-locale-downcase
Greek (two sigmas)"]: New tests.
* test-suite/standalone/Makefile.am:
* test-suite/standalone/test-mb-regexp: New test, that the previous
patch fixed the abort() on fixup_multibyte_match.
* libguile/foreign.c (scm_pointer_to_scm, scm_scm_to_pointer): New
functions, useful to pass and receive SCM values to and from foreign
functions.
* module/system/foreign.scm: Export the new functions.
* doc/ref/api-foreign.texi (Foreign Variables): Add docs.
* test-suite/tests/foreign.test ("pointer<->scm"): Tests.
* test-suite/tests/control.test: Use c&e tests for most test blocks.
Note that this did not catch the recent bug.
("reified continuations"): Add a new test for capturing partial
continuations containing pending call frames. Before these would
contain dynamic links pointing out of the continuation segment, which
would not be relocated; now, the dynamic links are only made when the
frames are activated.
Thanks to Wolfgang J Moeller for the bug report and test case.
* module/rnrs/io/ports.scm (transcoder-eol-style)
(transcoder-error-handling-mode): Export these.
(textual-port?): Implement this procedure and export it.
* module/rnrs.scm: Export these here as well.
* module/rnrs/io/ports.scm (port-transcoder): Implement this procedure.
(binary-port?): Treat only ports without an encoding as binary ports,
add docstring.
(standard-input-port, standard-output-port, standard-error-port):
Ensure these are created without an encoding.
(eol-style): Add `none' as enumeration member.
(native-eol-style): Switch to `none' from `lf'.
* test-suite/tests/r6rs-ports.test (7.2.7 Input ports)
(8.2.10 Output ports): Test binary-ness of `standard-input-port',
`standard-output-port' and `standard-error-port'.
(8.2.6 Input and output ports): Add test for `port-transcoder'.

* libguile/r6rs-ports.c (scm_get_string_n_x): Implement `get-string-n!'
in C for efficiency.
* libguile/r6rs-ports.h: Add prototype for this function.
* module/ice-9/binary-ports.scm: Export `get-string-n!'.
* module/rnrs/io/ports.scm (get-string-n): Implement based on
`get-string-n!'.
Export both `get-string-n!' and `get-string-n'.
* module/rnrs.scm: Also export these.
* test-suite/tests/r6rs-ports.test (8.2.9 Textual input): Add a few
tests for `get-string-n' and `get-string-n!'.

* module/srfi/srfi-9.scm (define-inlinable): When inlining, evaluate the
arguments only once. Reported by Andreas Rottmann; thanks to Andy
Wingo for the elegant solution.
* test-suite/tests/srfi-9.test ("side-effecting arguments"): New test
prefix.
The expansion of `define-inlinable' contained an expression, which made
SRFI-9's `define-record-type' fail in non-toplevel contexts ("definition
used in expression context").
* module/srfi/srfi-9.scm (define-inlinable): Get rid of apparently
useless expression in the expansion, so the expansion yields only
definitions. At the same time, use a space in the generated names to
lessen the chances of name conflicts, also avoiding -Wunused-toplevel
warnings.
* test-suite/tests/srfi-9.test (non-toplevel): New test verifying that
`define-record-type' works in non-toplevel context as well.
* doc/ref/srfi-modules.texi (SRFI-9 - define-record-type): Add
subsubsection noting that Guile does not enforce top-levelness.

* libguile/procs.c (scm_setter): Only get at the setter slot if the pure
generic actually has a setter. Needs test.
* test-suite/tests/goops.test ("defining generics"):
("defining accessors"): Add `setter' tests.
* module/language/tree-il/fix-letrec.scm (fix-letrec!): When X is a
`letrec*' with only lambdas and simple expressions, analyze it as if
it were a `letrec'.
* test-suite/tests/tree-il.test ("letrec"): Add test for
`(letrec* (x y) (xx yy) ((const 1) (const 2)) (lexical y yy))'.
* module/Makefile.am:
* module/ice-9/eval-string.scm: New module, for use in implementing the
scm_c_eval_string_from_file_line suggestion.
* test-suite/Makefile.am:
* test-suite/tests/eval-string.test: New tests.
* libguile/guile-snarf.in (modern_snarf): Allow programs to specify
multiple initialization actions on a single line. This makes it
possible for C programs to define multiple subrs with a single macro
invocation.
* test-suite/standalone/test-guile-snarf: Enable more tests.
* module/ice-9/boot-9.scm (module-use-interfaces!): Fix up to prevent
duplication in the use list of multiple incoming interfaces.
* test-suite/tests/modules.test ("module-use"): Add tests.
* test-suite/tests/popen.test (open-input-pipe no-duplicate): Pass
"read REPLY" command instead of "read" to the subshell, for improved
portability. In particular, it is needed when /bin/sh is dash.
(open-output-pipe no-duplicate): Pass "exec guile [...]" instead of
"guile [...]" to the subshell, to ensure that the subshell will not
run guile as a subprocess while holding a duplicate of STDIN, which
would cause this test to fail. This is needed when /bin/sh is dash.

of `scm_get_byte_or_eof'.
* test-suite/tests/reader.test ("read-options")["position of SCSH block
comment"]: New test.
* libguile/numbers.c (log_of_shifted_double, log_of_exact_integer,
log_of_exact_integer_with_size, log_of_fraction): New internal static
functions used by scm_log and scm_log10.
(scm_log, scm_log10): Robustly handle large integers, large and small
fractions, and fractions close to 1. Previously, computing logarithms
of fractions close to 1 yielded grossly inaccurate results, and the
other cases yielded infinities even though the answer could easily fit
in a double. (log -0.0) now returns -inf.0+<PI>i, where previously it
returned -inf.0. (log 0) now throws a numerical overflow exception,
where previously it returned -inf.0. (log 0.0) still returns -inf.0.
Analogous changes made to `log10'.

* libguile/numbers.c (scm_c_truncate): Use ceil (x) instead of
-floor (-x).
(scm_truncate_number): Implement directly instead of by checking the
sign and using scm_floor or scm_ceiling. Use scm_truncate_quotient
for fractions. Make extensible, so that new number types implemented
in GOOPS will be able to do the job more efficiently, since it is
often easier to implement truncate than floor or ceiling.
(scm_round_number): Optimize fractions case by using
scm_round_quotient. Make extensible, so that new number types
implemented in GOOPS will be able to do the job efficiently.
(scm_floor, scm_ceiling): Optimize fractions case by using
scm_floor_quotient and scm_ceiling_quotient, respectively.
* test-suite/tests/numbers.test: Add test cases.
* module/ice-9/boot-9.scm (the-scm-module): Make it its own public

"the-scm-module"]: New tests.
* libguile/numbers.c (scm_euclidean_quotient, scm_euclidean_divide,
scm_centered_quotient, scm_centered_divide): Fix bug in inum/inum
case, where (quotient most-negative-fixnum -1) would not be converted
to a bignum.
(scm_euclidean_quotient): Be more anal-retentive about calling
scm_remember_upto_here_1 after mpz_sgn, (even though mpz_sgn is
documented as being implemented as a macro and certainly won't
do any allocation). It's better to be safe than sorry here.
(scm_euclidean_quotient, scm_centered_quotient): In the bignum/inum
case, check if the divisor is 1, since this will allow us to avoid
allocating a new bignum.
(scm_euclidean_divide, scm_centered_quotient, scm_centered_divide):
When computing the intermediate truncated quotient (xx / yy) and
remainder, use (xx % yy) instead of (xx - qq * yy), on the theory that
the compiler is more likely to handle this case intelligently and
maybe combine the operations.
(scm_euclidean_divide): In the bignum/inum case, we know that the
remainder will fit in an fixnum, so don't bother allocating a bignum
for it.
(scm_euclidean_quotient, scm_euclidean_remainder,
scm_euclidean_divide, scm_centered_quotient, scm_centered_remainder,
scm_centered_divide): Minor stylistic changes.
* test-suite/tests/numbers.test: Rework testing framework for
number-theoretic division operators to be more efficient and
comprehensive in its testing of code paths and problem cases.
