+    Makefile.am: drop -Wno-implicit-function-declaration
+    
+    1. Clang 16 makes -Wimplicit-function-declaration error by default
+       (and it's planned that GCC 14 will do the same) so we need to fix
+       the real problem. This is papering over it.
+    
+    2. It's not true that there's nothing we can do about it. Fix in a follow-up
+       commit.
