+Subject: [PATCH] specify void prototype for functions with no parameters
+
+Compilers defaulting to C99 flag such functions as warning which fails
+to compile when using -Werror
+
+Fixes
+error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
