+Subject: [PATCH] Use `static inline` instead of `inline`
+
+`inline` by itself is not portably guaranteed to emit
+an external definition when needed in C99. The current
+code base implicitly relies on GNU89 inline semantics,
+which _always_ emit an external definition. More recent
+versions of GCC and Clang switch to C99/C11 inline semantics
+by default, which fails with undefined references.
