Without this fix, the command to link temacs failed due to an
undefined symbol __builtin_isnan. This is because
/usr/include/iso/math_c99.h #defines isnan(x) to
__builtin_isnan(x), but the bundled gcc, which identifies itself
as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
a __builtin_isnan.
* configure.in (isnan): Remove now-unnecessary check.
* src/floatfns.c (isnan): #undef, and then #define to a clone of
what's in data.c.
(Fisnan): Always define, since it's always available now.
(syms_of_floatfns): Always define isnan at the Lisp level.
* etc/grep.txt: Add `eval' to the Local Variables section that
emulates `grep-filter'.
* lisp/progmodes/grep.el (grep-filter): Avoid incomplete processing by
keeping point where processing of grep matches begins, and
continue to delete remaining escape sequences from the same point.
(grep-filter): Make leading zero optional in "0?1;31m" because
git-grep emits "\033[1;31m" escape sequences unlike expected
"\033[01;31m" as GNU Grep does.
(grep-process-setup): Replace obsolete "ml=" with newer "sl=".
Fixes: debbugs:9408
gnus.el (gnus-home-directory): Add warning about setting in .gnus.el (bug#9405).
gnus-score.el (gnus-summary-increase-score): Doc clarification (bug#9421).
gnus-spec.el (gnus-face-0): Make all the face specs into defcustoms (bug#9425).
gnus-art.el (gnus-treatment-function-alist): Remove CRs as the first thing (bug#9426).
(window_scroll_line_based, Frecenter):
Check that an Emacs fixnum is in range before assigning it to 'int'.
(Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
values converted from Emacs fixnums.
(Frecenter): Don't wrap around a line count if it is out of 'int'
range; instead, treat it as an extreme value.
(Fset_window_configuration, compare_window_configurations):
Use ptrdiff_t, not int, for index that might exceed 2 GiB.
`tramp-cache-unload-hook' where appropriate.
(tramp-methods): Rename `tramp-remote-sh' to
`tramp-remote-shell'. Add `tramp-remote-shell-args'.
(tramp-handle-shell-command): New defun, moved from tramp-sh.el.
* net/tramp-sh.el (top): Don't require 'shell.
(tramp-methods): Add `tramp-remote-shell' and
`tramp-remote-shell-args' entries.
(tramp-sh-file-name-handler-alist): Use `tramp-handle-shell-command'.
(tramp-sh-handle-shell-command): Remove.
(tramp-find-shell, tramp-open-connection-setup-interactive-shell):
Use `tramp-remote-shell'.
(Freplace_match): Use ptrdiff_t, not int, for indexes that can
exceed INT_MAX. Check that EMACS_INT value is in range before
assigning it to the (possibly-narrower) index.
(match_limit): Don't assume that a fixnum can fit in 'int'.
(position_indentation): Now takes ptrdiff_t, not int.
(Fvertical_motion): Don't wrap around LINES values that don't fit
in 'int'. Instead, treat them as extreme values. This is good
enough for windows, which can't have more than INT_MAX lines anyway.
* xml.c (parse_region): Don't call xmlCleanupParser after parsing,
since this reportedly can destroy thread storage.
* emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
* window.el (window-deletable-p): Don't return a non-nil value
when there's a buffer that was shown in the window before.
(Bug#9419)
(display-buffer-pop-up-frame, display-buffer-pop-up-window): Set
window's previous buffers to nil.
lisp/mail/rmailmm.el (rmail-mime-insert-tagline): Insert an extra
newline before and after the tag line, so it doesn't interfere
with determining the paragraph direction of bidirectional text.
The previous code assumed that file offsets (off_t values) fit in
EMACS_INT variables, which is not true on typical 32-bit hosts.
The code messed up by falsely reporting buffer overflow in cases
such as (insert-file-contents "big" nil 1 2) into an empty buffer
when "big" contains more than 2**29 bytes, even though this
inserts just one byte and does not overflow the buffer.
(Finsert_file_contents): Store file offsets as off_t
values, not as EMACS_INT values. Check for overflow when
converting between EMACS_INT and off_t. When checking for
buffer overflow or for overlap, take the offsets into account.
Don't use EMACS_INT for small values where int suffices.
When checking for overlap, fix a typo: ZV was used where
ZV_BYTE was intended.
(Fwrite_region): Don't assume off_t fits into 'long'.
* buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
