40f892156a Read complex numbers where both parts are inexact decimals 
Thanks to Bill Schottstaedt for reporting this problem!

* libguile/numbers.c (mem2ureal): Don't be misled by *p_exactness
  being INEXACT on entry (as is possible when reading a complex
  number): use local exactness variable x which starts as EXACT.
  Call mem2decimal_from_point () with &x instead of p_exactness.

* test-suite/tests/numbers.test ("string->number"): Add complex number
  tests suggested by Bill.

1dd797921c Fix for incorrect (gcd -2) => -2; should give 2. 
(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).

92d8fd328c Use `scm_gc_malloc_pointerless' in various places (improves performance). 
* libguile/fports.c (scm_fport_buffer_add): Use
  `scm_gc_malloc_pointerless ()' instead of `scm_gc_malloc ()' when
  allocating room for the read/write buffers.

* libguile/numbers.c (scm_c_make_rectangular): Likewise.

* libguile/ports.c (scm_ungetc): Likewise.

* libguile/random.c (scm_i_copy_rstate): Likewise.
  (scm_c_make_rstate): Likewise.

4b26c03ec7 * numbers.c (SCM_COMPLEX_VALUE): Use GUILE_I instead of _Complex_I 
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.

90709cd75f (scm_log): Test HAVE_CLOG as well as HAVE_COMPLEX_DOUBLE 
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.

e2bf3b19f6 * numbers.c (scm_i_fraction_reduce): move logic into 
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.

788aca275f (scm_ash): Rewrite using shifts, much faster than 
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.
