/* Target specific type definitions. */
-/* ??? Do we really want long as size_t on 31-bit? */
+/* For 31 bit our size type differs from most other targets (where it
+ is "unsigned int"). The difference tends to cause trouble e.g.:
+ Glibc BZ #16712, GCC BZ #79358 but cannot be changed due to ABI
+ issues. */
