commit https://github.com/vim/vim/commit/08b7bae91adb79d30d4c923fd758e2f7cecd33ef Author: Bram Moolenaar <Bram@vim.org> Date: Wed Dec 30 17:56:05 2015 +0100 patch 7.4.1004 Problem: Using Makefile when auto/config.mk does not exists results in warnings. Solution: Use default values for essential variables.

# The most simplistic Makefile for Win32 using Microsoft Visual C++
# (NT and Windows 95)

xxd: xxd.exe

xxd.exe: xxd.c
     cl /nologo -DWIN32 xxd.c

# This was for an older compiler
#    cl /nologo -DWIN32 xxd.c /link setargv.obj

clean:
     - if exist xxd.obj del xxd.obj
     - if exist xxd.exe del xxd.exe
