+ * backtrace.h (backtrace_syminfo_callback): Add symsize argument.
+ * elf.c (elf_syminfo): Pass 0 or sym->size to the callback as
+ last argument.
+ * btest.c (struct symdata): Add size field.
+ (callback_three): Add symsize argument. Copy it to the data->size
+ field.
+ (f23): Set symdata.size to 0.
+ (test5): Likewise. If sizeof (int) > 1, lookup address of
+ ((uintptr_t) &global) + 1. Verify symdata.val and symdata.size
+ values.
+
+ * atomic.c: Include sys/types.h.
