7351e20717 From John W. Eaton. 
* numbers.h: Conditionally include floatingpoint.h, ieeefp.h, and
nan.h.	Provide declarations for scm_inf_p, scm_nan_p, scn_inf,
and scm_nan.
* numbers.c: [SCO && ! HAVE_ISNAN] (isnan): New function.
[SCO && ! HAVE_ISINF] (isinf): New function.
(xisinf, xisnan): New functions.
(IS_INF): Delete.
(isfinite): Define in terms of xisinf.
(scm_inf_p, scm_nan_p): New functions.
(guile_Inf, guile_NaN): New file-scope vars.
(guile_ieee_init): New function.
(scm_inf, scm_nan): New functions.
(idbl2str): Handle Inf and NaN.	Remove funny label and
corresponding gotos.
(ALLOW_DIVIDE_BY_ZERO): New macro.
(scm_divide): Allow division by zero to occur if
ALLOW_DIVIDE_BY_ZERO is defined.
Handle bignums and ints as special cases.

Additional stuff by me:

numbers.c (mem2ureal): Recognize "inf.0" and "nan.xxx".
(scm_even_p, scm_odd_p): Treat infinity as even and odd.
(iflo2str): Don't output a '+' for negative numbers or for Inf and
NaN.  They will provide their own sign.
(scm_divide): Only allow divides by inexact zeros.  Dividing by
exact zeros still signals an errors.

c8519a82f2 (scm_string_tokenize): Instead of using "isgraphic" as the subtitute 
for char-set:graphic when then token-set hsa been defaulted, grab the

c517e17593 Initial revision. 
Differences between this and (ttn gap-buffer):
Use string-join; autoload (srfi srfi-13).
Values for `default-initial-allocation', `default-chunk-size'
and `default-realloc-threshold' are 4x as large.

87ea4cd389 Invoke plain aclocal instead of guile-aclocal.sh. We don't need the 
Guile m4 macros and the previous invocation of guile-aclocal.sh
created the aclocal.m4 file in the wrong directory (see change from
2002-04-26).
