+Subject: [PATCH] Avoid using char as loop variable. Signedness of char varies across platorms
+
+_factor entered an infinite loop on platforms where char is unsigned.
+
+generally better to use int as loop variable. It's both signed and the
+most efficient data type for simple integer calculations across the different
+cpu architectures.
