* 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.
Cramer for pointing out the disuse.)
* root.h (scm_root_state): removed def_inp, def_outp, def_errp.
* root.c (root_mark): don't mark them.
(scm_make_root): don't set them to #f.
* init.c (scm_init_standard_ports): don't initialise with the
default ports.
VPATH build, which is not allowed. It also isn't needed since it only
works when an output filename has been specified and in that case we
don't need to clean the input file because the output file will
already exist.
function, replaces macro SRCBRKP.
(SRCBRKP): Deprecated.
* eval.c (SCM_CEVAL): Replaced use of SRCBRKP by call to
scm_c_source_property_breakpoint_p. Removed some use of arg1 as
temporary variable.
is given, use "-" as the output filename (i.e., stdout). Only 'clean'
the inputfile or remove the output file on error when the output file
name is not "-". Define the preprocessor macro SCM_MAGIC_SNARFER
while snarfing.
(SCM_CEVAL): Minimized scope of variable orig_sym. Eliminated
goto-labels cdrxnoap, cdrxbegin and nontoplevel_cdrxnoap. Changed
argument checking order for set! to locals, variables and symbols.
Improvements to control structure. Removed some uses of arg1 and
arg2 as temporary variables.
Add "-d" and "-D" support.
(deprecated_list): New var.
(compat_mode_clean_xxx): Delete.
(grep_deprecated): New func.
("main"): If "-d" or "-D", call `grep_deprecated'.
