patch 8.0.0199: compiler warnings for libcall
commit https://github.com/vim/vim/commit/6d721c7e10251ad8c89a461eed99d8cf2659c1df
Author: Bram Moolenaar <Bram@vim.org>
Date: Tue Jan 17 16:56:28 2017 +0100
patch 8.0.0199: compiler warnings for libcall
Problem: Warning for an unused parameter when the libcall feature is
disabled. Warning for a function type cast when compiling with
-pedantic.
Solution: Add UNUSED. Use a different type cast. (Damien Molinier)
