Comment at: lib/builtins/muloti4.c:56
     {
-        if (abs_a > MIN / -abs_b)
+        if (abs_a > __divti3(MIN, -abs_b))
             *overflow = 1;
----------------
I find this and related changes to be not acceptable. It hard-codes the assumption that the division is not lowered natively by the compiler, which is IMO not valid.
