From 6b10721fa2d883540c1c106ef26fff8abed0ac43 Mon Sep 17 00:00:00 2001
From: Bram Moolenaar <Bram@vim.org>
Date: Wed, 11 Dec 2013 15:06:40 +0100
Subject: updated for version 7.4.117 Problem:    Can't build with Cygwin/MingW
 and Perl 5.18. Solution:   Add a linker argument for the Perl library. (Cesar
 Romani)             Adjust CFLAGS and LIB. (Cesar Romani)             Move
 including inline.h further down. (Ken Takata)
