+Subject: [PATCH] internal: declare match_no_control() inline instead of static
+
+Newer clang (23+) enables -Wunused-template for namespace-scope static
+function templates defined in headers. match_no_control() is only ever
+referenced from other templates, so in any translation unit where none of
+those get instantiated the internal-linkage template is genuinely unused
+and the -Werror test build fails:
+
+  include/tao/pegtl/internal/match_impl.hpp:24:30: error: unused function
+    template 'match_no_control' [-Werror,-Wunused-template]
+
+This breaks every test in src/test, since they are all compiled with
+-Wall -Werror.
+
+Declare the two overloads inline instead; that is the correct linkage for
+a function template defined in a header and does not trigger the warning.
+
+Upstream-Status: Pending
