The porting part of this patch fixes bugs on non-IEEE platforms
with frexp, ldexp, logb.
* admin/CPP-DEFINES (HAVE_CBRT, HAVE_LOGB, logb): Remove.
* configure.ac (logb, cbrt): Do not check for these functions,
as they are not being used.
* doc/lispref/numbers.texi (Float Basics, Arithmetic Operations, Math Functions):
Document that / and mod (with floating point arguments), along
with asin, acos, log, log10, expt and sqrt, return special values
instead of signaling exceptions.
(Float Basics): Document that logb operates on the absolute value
of its argument.
(Math Functions): Document that (log ARG BASE) also returns NaN if
BASE is negative. Document that (expt X Y) returns NaN if X is a
finite negative number and Y a finite non-integer.
* etc/NEWS: Document NaNs versus signaling-error change.
* src/data.c, src/lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
Now static.
* src/floatfns.c: Simplify discussion of functions that Emacs doesn't
support, by removing commented-out code and briefly listing the
C89 functions excluded. The commented-out stuff was confusing
maintenance, e.g., we thought we needed cbrt but it was commented out.
(logb): Remove decl; no longer needed.
(isfinite): New macro, if not already supplied.
(isnan): Don't replace any existing macro.
(Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
are present on all C89 platforms.
(Ffrexp): Do not special-case zero, as frexp does the right thing
for that case.
(Flogb): Do not use logb, as it doesn't have the desired meaning
on hosts that use non-base-2 floating point. Instead, stick with
frexp, which is C89 anyway. Do not pass an infinity or a NaN to
frexp, to avoid getting an unspecified result.
* lisp/replace.el (query-replace-map): Bind four new symbols for
requesting window scrolling.
* lisp/subr.el (y-or-n-p): Handle the window-scrolling bindings in
query-replace-map.
* lisp/custom.el (custom-theme-load-confirm): Use y-or-n-p.
* lisp/window.el (scroll-other-window-down): Make the arg optional.
* lisp/emacs-lisp/map-ynp.el (map-y-or-n-p): Don't bind scrolling keys
since they are now in query-replace-map.
* doc/lispref/minibuf.texi (Yes-or-No Queries): Document recentering and
scrolling in y-or-n-p. Remove gratuitous example.
* doc/lispref/searching.texi (Search and Replace): Document window scrolling
entries in query-replace-map.
Fixes: debbugs:8948
* lisp/subr.el (buffer-narrowed-p): New function.
* lisp/ses.el (ses-widen):
* lisp/simple.el (count-words--buffer-message):
* lisp/net/browse-url.el (browse-url-of-buffer): Use it
* lisp/simple.el (count-words-region): Don't signal an error if there
is a non-nil prefix arg and the mark is not set.
* doc/lispref/positions.texi (Narrowing): Document buffer-narrowed-p.
This allows tracking down what piece of code is outputting stuff in
the echo area.
* eval.c (call_debugger): Make the function non-static so that we
can call it from set_message.
* xdisp.c (set_message): Implement the new variable `debug-on-message'.
(syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
* doc/lispref/numbers.texi (Random Numbers): Document new behavior of
the calls (random) and (random STRING).
* etc/NEWS: Document new behavior of (random), (random "string").

* lisp/type-break.el (type-break):
Remove unnecessary call to (random t).

* lisp/gnus/gnus-sync.el (gnus-sync-lesync-setup):
* lisp/gnus/message.el (message-canlock-generate, message-unique-id):
Change (random t) to (random), now that the latter is more random.
* lisp/org/org-id.el (org-id-uuid):
Change (random t) to (random), now that the latter is more random.
* src/emacs.c (main): Call init_random.
* src/fns.c (Frandom): Set the seed from a string argument, if given.
Remove long-obsolete Gentzel cruft.
* src/lisp.h, src/sysdep.c (seed_random): Now takes address and size, not long.
(init_random): New function.
doc/lispref/functions.texi (Closures): Put the main index entry for
"closures" here.
