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/
