+
+ Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
+ 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.

+ (x_session_initialize): Do not assume string length fits in int.
+
+ * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
+ This is unlikely, but can occur if DPI is outlandish.
+
+ * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
+ * xselect.c (Fx_get_atom_name): Avoid need for strlen.
+
+ * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
+ * xrdb.c (magic_file_p, search_magic_path):
+ Omit last arg SUFFIX; it was always 0. All callers changed.

* filelock.c: Fix some buffer overrun and integer overflow issues.
- (get_boot_time): Don't assume that gzip command string fits in 100 bytes.
+ (get_boot_time): Don't assume gzip command string fits in 100 bytes.
Reformulate so as not to need the command string.
Invoke gzip -cd rather than gunzip, as it's more portable.
(lock_info_type, lock_file_1, lock_file):
Check for time_t and/or pid_t out of range, e.g., via a network share.
Don't alloca where an auto var works fine.

-
* fileio.c: Fix some integer overflow issues.
(file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
Don't assume string length fits in int.
All uses changed. This doesn't fix a bug, but it simplifies the
code away from its former Hollerith-constant appearance, and it's
one less 'int' to worry about when looking at integer-overflow issues.
- (string_to_number): Simplify the 2011-04-26 change by invoking xsignal1.
+ (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.

(LIST_END_P): Remove unused macro and its bogus comment.
(make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
-2011-06-18 Paul Eggert <eggert@cs.ucla.edu>
