* process.c (wait_reading_process_output): Bypass select if
waiting for a cell while ignoring keyboard input, and input is
pending. Suggested by Jan Djärv.
* Makefile.in (GNULIB_MODULES): Add dup2.
* configure.in: Do not check for dup2; gnulib does that now.
* lib/dup2.c, m4/dup2.m4: New files, from gnulib.
* src/sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
* keyboard.h (struct keyboard.kbd_macro_bufsize):
* macros.c (Fstart_kbd_macro, store_kbd_macro_char):
Use ptrdiff_t, not int, for sizes.
Don't increment bufsize until after realloc succeeds.
Check for size-calculation overflow.
(Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
(Fload, openp, read_buffer_size, read1)
(substitute_object_recurse, read_vector, read_list, map_obarray):
Use ptrdiff_t, not int, for sizes.
(read1): Use EMACS_INT, not int, for sizes.
(read_integer): Radix is now EMACS_INT, not int,
to improve quality of diagnostics for out-of-range radices.
Calculate buffer size correctly for out-of-range radices.
(read1): Check for integer overflow in radices, and in
read-circle numbers.
The following patches are for when GLYPH_DEBUG && !XASSERT.
* dispextern.h (trace_redisplay_p, dump_glyph_string):
* dispnew.c (flush_stdout):
* xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
Mark as externally visible.
* dispnew.c (check_window_matrix_pointers): Now static.
* dispnew.c (window_to_frame_vpos):
* xfns.c (unwind_create_frame):
* xterm.c (x_check_font): Remove unused local.
* scroll.c (CHECK_BOUNDS):
* xfaces.c (cache_fache): Rename local to avoid shadowing.
* xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
* xdisp.c (check_window_end): Now a no-op if !XASSERTS.
(debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
(debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
Now static.
(debug_method_add): Use va_list and vsprintf rather than relying
on undefined behavior with wrong number of arguments.
(dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
Don't assume ptrdiff_t and EMACS_INT are the same width as int.
In this code, it's OK to assume C99 behavior for ptrdiff_t formats
since we're not interested in debugging glyphs with old libraries.
* xfaces.c (cache_face): Move debugging code earlier; this pacifies
GCC 4.6.0's static checking.
* composite.c (find_automatic_composition): Omit needless 'return 0;'
that Sun C diagnosed.
* fns.c (secure_hash): Fix pointer signedness issue.
* intervals.c (static_offset_intervals): New function.
(offset_intervals): Use it.
* xrdb.c (magic_file_p, search_magic_path):
Omit last arg SUFFIX; it was always 0. All callers changed.
(magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
not unsigned long, as we prefer signed integers. All callers changed.
Detect integer overflow in repeat count.
(message_dolog): Don't assume print length fits in 39 bytes.
