+ * alloc.c: Use EMACS_INT, not int, to count objects.
+ (total_conses, total_markers, total_symbols, total_vector_size)
+ (total_free_conses, total_free_markers, total_free_symbols)
+ (total_free_floats, total_floats, total_free_intervals, total_intervals)
+ (total_strings, total_free_strings):
+ Now EMACS_INT, not int. All uses changed.
+ (Fgarbage_collect): Compute overall total using a double, so that
+ integer overflow is less likely to be a problem. Check for overflow
+ when converting back to an integer.
+ (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
+ (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
+ These were 'int' variables that could overflow on 64-bit hosts;
+ they were never used, so remove them instead of repairing them.
+ (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
+ (inhibit_garbage_collection): Set gc_cons_threshold to max value.
+ Previously, this ceilinged at INT_MAX, but that doesn't work on
+ 64-bit machines.
+ (allocate_pseudovector): Don't use EMACS_INT when int would do.
+
* alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
(allocate_vectorlike): Check for ptrdiff_t overflow.
(mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
