+Subject: [PATCH] Fix the build issue with gperf 3.1
+
+To support the one of changes in gperf 3.1:
+* The 'len' parameter of the hash function and of the lookup function is now
+  of type 'size_t' instead of 'unsigned int'. This makes it safe to call these
+  functions with strings of length > 4 GB, on 64-bit machines.
