+ Don't assume time_t can fit into int.
+ * buffer.h (struct buffer.modtime): Now time_t, not int.
+ * fileio.c (Fvisited_file_modtime): No need for time_t cast now.
+ * undo.c (Fprimitive_undo): Use time_t, not int, for time_t value.
+
+ Minor fixes for signed vs unsigned integers.
+ * character.h (MAYBE_UNIFY_CHAR):
+ * charset.c (maybe_unify_char):
+ * keyboard.c (read_char, reorder_modifiers):
+ XINT -> XFASTINT, since the integer must be nonnegative.
+ * ftfont.c (ftfont_spec_pattern):
+ * keymap.c (access_keymap, silly_event_symbol_error):
+ XUINT -> XFASTINT, since the integer must be nonnegative.
+ (Fsingle_key_description, preferred_sequence_p): XUINT -> XINT,
+ since it makes no difference and we prefer signed.
+ * keyboard.c (record_char): Use XUINT when all the neighbors do.
+ (access_keymap): NATNUMP -> INTEGERP, since the integer must be
+ nonnegative.

Malloc failure behavior now depends on size of allocation.
