* doc/ref/api-options.texi (Build Config):
* doc/ref/libguile-linking.texi (Linking Programs With Guile):
(A Sample Guile Main Program):
* doc/ref/libguile-smobs.texi (The Complete Example): Use pkg-config in
the examples instead of guile-config.
* doc/ref/history.texi (A Timeline of Selected Guile Releases): Update
the 2.0 release blurb.
* doc/ref/api-foreign.texi (Modules and Extensions):
* doc/ref/libguile-extensions.texi (A Sample Guile Extension):
* doc/ref/tour.texi (Linking Guile into Programs): Use
@value{EFFECTIVE-VERSION} instead of 2.0. Also fix sample extension
compilation line to include the Guile CFLAGS.
* doc/ref/goops.texi (Class Definition Protocol): Removed `*fixme
Need to insert something here about checking that the value is not
unbound'. It's a fine detail, and also I imagine there could be a
valid application that would choose to allow SCM_GOOPS_UNBOUND
values to escape through here.
* doc/ref/goops.texi (Method Definition): Unindent text about
define-method invoking add-method!.
(Method Definition Internals): Add @noindent's.
(Generic Function Invocation): Add intro text, and tidy up the tree.
* doc/ref/goops.texi (Class Redefinition): Deleted, with its material
all merged into later `Redefining a Class' and `Changing the Class of
an Instance' sections.
* doc/ref/goops.texi (Instance Creation Protocol): Rename from
`Customizing Instance Creation', and move before the more
complicated class definition stuff. Couple of very minor edits.
(Class Definition Protocol): Remove ensure-metaclass-with-supers
(too internal) and repeated material. Move class-redefinition
stuff to (existing) later section on that. Merge reference-like
material from `Customizing Class Definition' to here.
* doc/ref/goops.texi (The Metaobject Protocol): Simplify intro text.
Minor edits and simplifications throughout this section.
(Metaobjects and the Metaobject Protocol): Insert "default".
(Metaclasses): Renamed from `Terminology', and deleted the material
on CPL and accessors, which just duplicated what has already been
covered earlier in the chapter. Remove statements that confuse
whether "metaclass of" means "class of class of" or "class of
(something that is itself a class)". (I think it's actually the
latter.)
(Class Definition Protocol): Renamed from `Class Definition
Internals'.
* libguile/ports.c (scm_i_remove_port): Fix a case in which ports
explictly closed via close-port would leak their iconv_t data.
(scm_set_port_encoding_x): scm_i_set_port_encoding_x strdups its
argument, so we need to free the locale encoding of the incoming str.
* module/ice-9/binary-ports.scm: New module.
* module/Makefile.am: Add to makefile.
* module/rnrs/io/ports.scm: Re-export bindings from (ice-9 binary
ports). This will allow the compiler to not pull (rnrs) into its
included module set.
* 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'.
* test-suite/tests/numbers.test (log, log10): Add tests.

* libguile/numbers.c (scm_i_inexact_truncate_divide): Use trunc instead
of floor and ceil. Important for consistency with
scm_truncate_quotient and scm_truncate_remainder.
Signed-off-by: Ludovic Courtès <ludo@gnu.org>
* libguile/Makefile.am (c-tokenize.$(OBJEXT)): When cross-compiling,
don't include any CPPFLAGS since we could end up seeing Gnulib's
replacements, e.g., `rpl_malloc', which we can't use.
* libguile/Makefile.am (version_info): New variable.
(libguile_@GUILE_EFFECTIVE_VERSION@_la_LIBADD): Remove
`$(LTLIBUNISTRING) $(LTLIBICONV) $(LTLIBINTL)'.
(libguile_@GUILE_EFFECTIVE_VERSION@_la_LDFLAGS): Add all the flags
from Gnulib, one per line as in the `gnulib-tool' output, including
those above.
From Gnulib v0.0-4889-ge375fe3.
* m4/gnulib-cache.m4: Add `log1p' and `round', requested by
Mark H Weaver <mhw@netris.org>.
Use `malloc-gnu' instead of `malloc', the latter being obsolete.
* libguile/numbers.c (scm_c_truncate, scm_truncate_number,
scm_i_inexact_truncate_quotient, scm_i_inexact_truncate_remainder):
Use trunc directly, now that we have its gnulib module.
* doc/ref/api-data.texi (Arithmetic): The R5RS `quotient', `remainder',
and `modulo' operators are exact-integer-only operators. `modulo' is
equivalent to `floor-remainder', not `floor-quotient'.
* module/oop/goops.scm (ensure-generic): If the old definition of a
desired getter is a primitive generic, let the new method be added to
it instead of creating a fresh new generic.
(ensure-accessor): Modify as necessary to keep the old behavior.
Maybe something more optimal can be done here, but it's not yet
obvious to me how to do it.
* libguile/numbers.h (SCM_NUMP, SCM_NUMBERP): Mask out more bits in the
cell type field when doing the comparison, in order to accept future
numeric types that have not yet been implemented. This should allow
us to add more core numeric types without breaking ABI compatibility.
As a bonus, these macros are now more efficient.
* libguile/numbers.c (scm_quotient): Reimplement in terms of
scm_truncate_quotient.
(scm_remainder): Reimplement in terms of scm_truncate_remainder.
(scm_modulo): Reimplement in terms of scm_floor_remainder.
(scm_euclidean_quotient, scm_euclidean_remainder,
scm_euclidean_divide): Reimplement in terms of floor and ceiling.
Make them non-extensible, because there is no need; they will work
with any objects that implement the floor and ceiling division
operators, and that can be tested using `negative?'.
* 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.
* libguile/numbers.c: (scm_euclidean_quotient, scm_euclidean_remainder,
scm_euclidean_divide, scm_centered_quotient, scm_centered_remainder,
scm_centered_divide): Optimize case where both arguments are exact and
at least one is a fraction, by reducing to a subproblem involving only
integers, and then adjusting the resulting remainder as needed.
