+Subject: [PATCH] Include <stdint.h> where needed
+
+The {u,}int{8,16,32}_t types are defined in <stdint.h>, so it should be
+included when such types are used.
+
+Not including <stdint.h> might work by accident with some C libraries
+due to it being included by other headers, but it for example causes
+build failures with the musl C library.
