+    lib/package_unpack.c: silence gcc false positive
+    
+    On some systems, something like this happens:
+    
+    package_unpack.c:375:11: error: 'buf' may be used uninitialized in this function
+    
+    This is not actually a bug as logically `buf` is always initialized
+    in that place, but gcc doesn't like it anyway.
