commit https://github.com/vim/vim/commit/7a84dbe6be0ef0e1ffbb7148cfe4ab50b9ba8f41 Author: Bram Moolenaar <Bram@vim.org> Date: Sun Feb 7 21:29:00 2016 +0100 patch 7.4.1286 Problem: ch_open() with a timeout doesn't work correctly. Solution: Change how select() is used. Don't give an error on timeout. Add a test for ch_open() failing.

# 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
