colors available for a display based on the display's number of
planes and number of bits per pixel per plane.  (bug#10397).

 src/ralloc.c (relinquish): If a heap is ready to be relinquished,
 but it still has blocs in it, don't return it to the system,
 instead of aborting.  (Bug#12402)

* configure.ac (sys_siglist): Look for its decl in <signal.h>.
Otherwise, it's not found in either Fedora 17 or Solaris 11.
* src/sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
defined as a macro, as is done in Solaris.
(sys_siglist_entries): New macro.
(save_strsignal): Use it.
* src/syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.

Restore tool bar height when leaving fullscreen.
(canBecomeMainWindow): New function.

 src/w32proc.c (stop_timer_thread): Fix declaration of 'err'.

 src/w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
 that time stamps of directories could also be changed.  Don't
 request the too broad GENERIC_WRITE, only the more restrictive
 FILE_WRITE_ATTRIBUTES access rights.
 src/fileio.c (Fset_file_times): Special-case ignoring errors for
 directories only on MSDOS, not on MS-Windows.

 src/w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to

to avoid similar races.
* keyboard.c (pending_signals): Now bool, not int.

that caused Emacs to hang on Fedora 17 when profiling Lisp.

 src/w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
 consistent with the change in return value of 'safe_strsignal'.

 nt/preprep.c (RVA_TO_PTR): Cast the result to 'void *', to avoid
 compiler warnings when using the value.

* bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)

Now 'static', not 'static inline'.

* lisp/profiler.el (profiler-sampling-interval): Change units
from ms to ns, multiplying the default by 1000000 so that
it remains 1 ms.
(profiler-report-cpu-line-format): Give enough room for
the maximum counters on 64-bit hosts.
(profiler-report-render-calltree-1): Call them "CPU samples",
not "Time (ms)", since they are not milliseconds now (and
never really were).
* src/profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
Give extra weight to samples after overruns, to attempt to count
the time more accurately.
(setup_cpu_timer): Change sampling interval units from ms to ns, since
the underlying primitives nominally do ns.
(Fprofiler_cpu_start): Document the change.  Mention that
the sampling intervals are only approximate.

(fix_start_end_in_overlays): Remove redundant recentering.

* src/buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
(Fmake_overlay): Remove redundant tests.

case for the special 0 coding-system.
* src/frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.

A signal can arrive in the middle of a malloc, and Emacs's signal
handler can invoke strsignal, which can invoke malloc, which is
not portable.  This race condition bug makes Emacs hang on GNU/Linux.
Fix it by altering the signal handler so that it does not invoke
strsignal.
* emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
* process.c (status_message): Use const pointer, in case strsignal
is #defined to safe_strsignal.
* sysdep.c (sys_siglist, init_signals): Always define and
initialize a substitute sys_siglist if the system does not define
one, even if HAVE_STRSIGNAL.
(safe_strsignal): Rename from strsignal.  Always define,
using sys_siglist.  Return a const pointer.
* syssignal.h (safe_strsignal): New decl.
(strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.

 src/w32proc.c (timer_loop): Fix code that waits for timer
 expiration, to avoid high CPU usage.

(sweep_weak_table): Remove redundant prototypes.

 src/emacs.c: Move the inclusion of TERM_HEADER after including
 windows.h on WINDOWSNT.  This avoids compilation problems with
 MSVC.

 nt/preprep.c (RVA_TO_PTR): Use 'unsigned char *' instead of
 'void *', for pointer arithmetics.
 (OFFSET_TO_RVA, RVA_TO_OFFSET, RVA_TO_SECTION_OFFSET): Enclose all
 macro arguments in parentheses.

 src/unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
 as the previous version used 'void *'.
 src/ralloc.c (ROUNDUP): Fix last change.
 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
 'size_t'.

Fixes: debbugs:12544

 src/w32proc.c (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
 return results.
 [!HAVE_SETITIMER]: Behave as the previous version that didn't
 support timers.
