+Subject: [PATCH] Fix incompatible function pointer types
+
+Clang 16 (and likely GCC 14) will enforce strict C99 semantics
+  and break old K&R C declarations and require correct C89
+  function prototypes.
+
+Bug: https://bugs.gentoo.org/880809
+Clang: https://discourse.llvm.org/t/configure-script-breakage-with-the-new-werror-implicit-function-declaration/65213/9
+
+Patch has been sent to upstream here: https://sourceforge.net/p/aewan/bugs/14/
