+dnl -----------------------------------------
+dnl Similar to AC_CHECK_FUNC, but on systems that do not generate
+dnl warnings for missing prototypes (e.g. FreeBSD when compiling without
+dnl -Wall), it does not work.  By looking for function definition in
+dnl libraries, this problem can be worked around.
