+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?
