(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().
(clog, cexp, carg): Remove fallback definitions. These only
duplicated the code within scm_log and scm_exp, and the latter have to
exist for the case when there's no "complex double". So better just
fix up the conditionals selecting between the complex funcs and plain
doubles than worry about fallbacks.
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.
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.

* srfi-1.c, srfi-1.h: Renamed any 'lst1' into 'list1' because
lst1 is a #define on Win32 systems.
