commit https://github.com/vim/vim/commit/e8aee7dcf9b12becff86e8ce1783a86801c5f9f6 Author: Bram Moolenaar <Bram@vim.org> Date: Tue Apr 26 21:39:13 2016 +0200 patch 7.4.1793 Problem: Some character classes may differ between systems. On OS/X the regexp test fails. Solution: Make this less dependent on the system. (idea by Kazunobu Kuriyama)

# 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
