+
+No, I didn't test -- except by building glibc. (There are other
+problems at the moment, AFAICT, with actually running the library on ARM.)
+
+However, you're definitely correct -- good catch! -- and, in fact, in
+looking at my logs I see compiler warnings about the mismatched type
+assignment. Here is a more plausible version. How about this one?

+Thanks,
