(reported by Bill Schottstaedt)
* libguile/numbers.c (scm_gcd): When only one arg given, use scm_abs
to ensure that result is non-negative.
* test-suite/tests/numbers.test ("gcd"): New test, (gcd -2).
directly, and only if GUILE_I was defined by the configure step.
(scm_log, scm_log10, scm_exp, scm_sqrt): Use SCM_COMPLEX_VALUE
code only if SCM_COMPLEX_VALUE is defined.
* configure.in (--without-64-calls): Use AC_MSG_CHECKING and
AC_MSG_RESULT instead of just echo.
(GUILE_I): New programs to try using _Complex_I or 1.0fi for the
imaginary unit.
before using clog(). It's possible for gcc to provide the "complex
double" type, but for the system not to have the complex funcs.
(scm_exp): Ditto HAVE_CEXP for cexp().
scm_i_make_ratio(), so fractions are only read.
scm_i_fraction_reduce() modifies a fraction when reading it. A
race condition might lead to fractions being corrupted by reading
them concurrently.
* numbers.h: remove SCM_FRACTION_SET_NUMERATOR,
SCM_FRACTION_SET_DENOMINATOR, SCM_FRACTION_REDUCED_BIT,
SCM_FRACTION_REDUCED_SET, SCM_FRACTION_REDUCED_CLEAR,
SCM_FRACTION_REDUCED.
rather than converting to doubles, to avoid inf or nan when the inputs
are too big for a double but the quotient does fit. This affects
conversions exact->inexact of big fractions.
integer-expt and multiply/divide. Inexacts and fractions no longer
supported (they happened to work before for left shifts, but not
right). Don't really need inexacts and fractions, since ash is
documented as a "bitwise operation", and all the rest of those only
take exact integers.
scm_t_intmax values.
(scm_uint2str): New, for scm_t_uintmax.
(scm_iint2str): Argument type changed to scm_t_intmax,
reimplemented in terms of scm_uint2str.
* configure.in (isinf): Let configure find the isinf() function
on MinGW32 systems.

* threads.c (scm_threads_mark_stacks): Fixed local variable
definitions.
* strings.c (scm_i_substring_copy, s_scm_string_append): Fixed
local variable definitions.
* stime.c (_POSIX_C_SOURCE): Do not define this item on
MinGW32 because it conflicts with its pthread headers.
(s_scm_mktime): Consider the HAVE_STRUCT_TM_TM_ZONE define.
(s_scm_strftime): Using scm_from_locale_string() instead of
scm_makfrom0str().
* posix.c (s_scm_putenv): Fixed typo in the !HAVE_UNSETENV
part.
* numbers.c (scm_init_numbers): Removed check_sanity() call
inside GUILE_DEBUG. The function has been removed somewhen...
* filesys.c (_POSIX_C_SOURCE): Do not define this item on
MinGW32 because it conflicts with its pthread headers.
2004-09-03 Stefan Jahn <stefan@lkcc.org>
* srfi-1.c, srfi-1.h: Renamed any 'lst1' into 'list1' because
lst1 is a #define on Win32 systems.
(SCM_VALIDATE_STRING_COPY): Deprecated. Replaced all uses with
SCM_VALIDATE_STRING plus SCM_I_STRING_CHARS or
scm_to_locale_string, etc.
(SCM_VALIDATE_SUBSTRING_SPEC_COPY): Deprecated. Replaced as
above, plus scm_i_get_substring_spec.
* regex-posix.c, read.c, random.c, ramap.c, print.c, numbers.c,
hash.c, gc.c, gc-card.c, convert.i.c, backtrace.c, strop.c,
strorder.c, strports.c, struct.c, symbols.c, unif.c, ports.c: Use
SCM_I_STRING_CHARS, SCM_I_STRING_UCHARS, and SCM_I_STRING_LENGTH
instead of SCM_STRING_CHARS, SCM_STRING_UCHARS, and
SCM_STRING_LENGTH, respectively. Also, replaced scm_return_first
with more explicit scm_remember_upto_here_1, etc, or introduced
them in the first place.
(scm_number_p): Export as "number?" to Scheme.
(scm_is_complex, scm_is_number): New.
(scm_c_make_rectangular, scm_c_make_polar): New.
(scm_make_rectangular, scm_make_polar): Use above.
(scm_c_real_part, scm_c_imag_part, scm_c_magnitude, scm_c_angle):
New.
(scm_make_complex): Discouraged by moving to discouraged.h and
discouraged.c. Replaced all uses with scm_c_make_rectangular.
(scm_i_short2big, scm_i_int2big, scm_i_uint2big, scm_i_size2big,
scm_i_ptrdiff2big, scm_i_long_long2big, scm_i_ulong_long2big):
Removed prototypes.
(scm_make_real, scm_num2dbl, scm_float2num, scm_double2num):
Discouraged by moving to discouraged.h and discouraged.c.
Replaced all uses with scm_from_double.
(scm_num2float, scm_num2double): Discouraged by moving prototype
to discouraged.h and rewriting in terms of scm_to_double.
Replaced all uses with scm_to_double.
(scm_to_double): Do not implement in terms of scm_num2dbl, use
explicit code.
(scm_from_double): Do not implement in terms of scm_make_real, use
explicit code.
