commit https://github.com/vim/vim/commit/b7604cc19fa1db6a8182546bf662aa13d4574d7a Author: Bram Moolenaar <Bram@vim.org> Date: Fri Jan 15 21:23:22 2016 +0100 patch 7.4.1098 Problem: Still using old style C function declarations. Solution: Always define __ARGS() to include types. Turn a few functions into ANSI style to find out if this causes problems for anyone.

/*
 * An extremely simple program to make the cursor blink in an xterm.
 * This is useful when the cursor is hard to spot in a highlighted file.
 * Start in the background: "blink&"  Stop by killing it.
 * Bram Moolenaar  980109  (based on an idea from John Lange).
