commit https://github.com/vim/vim/commit/25e4fcde767084d1a79e0926bc301c92987c0cce Author: Bram Moolenaar <Bram@vim.org> Date: Sat Jan 9 14:57:47 2016 +0100 patch 7.4.1065 Problem: Cannot use the "dll" options on MS-Windows. Solution: Support the options on all platforms. Use the built-in name as the default, so that it's clear what Vim is looking for.

#! /bin/sh
#
# which.sh -- find where an executable is located.  It's here because the
# "which" command is not supported everywhere.  Used by Makefile.
