Use libwaio to read from pipes (stdin or named pipes) on Windows. This liberates us from nasty issues, such as pipes (as created by most programs) not being possible to read in a non-blocking or event-driven way. Although it would be possible to do that in a somewhat sane way on Vista+, it's still not easy, and on XP it's especially hard. libwaio handles these things for us. Move pipe.c to pipe-unix.c, and remove Windows specific things. Also adjust the input.c code to make this work cleanly.

Cross Compiling to Windows
Cross compiling mpv to Windows is supported with MinGW-w64. This can be used to produce both 32 bit and 64 bit executables. MinGW-w64 is available from http://mingw-w64.sourceforge.net.
You have to run mpv's configure with these arguments:
DEST_OS=win32 TARGET=i686-w64-mingw32 ./waf configure
While building a complete MinGW-w64 toolchain yourself is possible, people have created scripts to help ease the process. These are the two recommended methods:
- Using mingw-w64-cmake to setup a MinGW-w64 environment. We recommend you to try this first before MXE. mingw-w64-cmake will also build mpv and its dependencies.
- Alternatively, you can use MXE: http://mxe.cc. With MXE, you have to manually set the target to MinGW-w64 (even if you compile to 32 bit). A working example below.
Warning: the original MinGW (http://www.mingw.org) is unsupported.
Note that MinGW environments included in Linux distributions are often broken, outdated and useless, and usually don't use MinGW-w64.
Additional dependencies
You need a pthread wrapper. It must be interoperable with native Windows threads. pthreads-win32 or MinGW pthreads might work.
If you want --input-file=... to work, you need libwaio. It's available
from: git://midipix.org/waio
Example with MXE
# Download MXE. Note that compiling the required packages requires about 1.4 GB
# or more!
cd /opt
git clone https://github.com/mxe/mxe mingw
cd mingw
# Set build options.
# The JOBS environment variable controls threads to use when building. DO NOT
# use the regular `make -j4` option with MXE as it will slow down the build.
# Alternatively, you can set this in the make command by appending "JOBS=4"
# to the end of command:
echo "JOBS := 4" >> settings.mk
# The MXE_TARGET environment variable builds MinGW-w64 for 32 bit targets.
# Alternatively, you can specify this in the make command by appending
# "MXE_TARGETS=i686-w64-mingw32" to the end of command:
echo "MXE_TARGETS := i686-w64-mingw32" >> settings.mk
# If you want to build 64 bit version, use this:
# echo "MXE_TARGETS := x86_64-w64-mingw32" >> settings.mk
# Build required packages. The following provide a minimum required to build
# mpv.
make gcc ffmpeg libass jpeg pthreads
# Add MXE binaries to $PATH
export PATH=/opt/mingw/usr/bin/:$PATH
# Build mpv. The target will be used to automatically select the name of the
# build tools involved (e.g. it will use i686-w64-mingw32-gcc).
cd ..
git clone https://github.com/mpv-player/mpv.git
cd mpv
DEST_OS=win32 TARGET=i686-w64-mingw32 ./waf configure
# Or, if 64 bit version,
# DEST_OS=win32 TARGET=x86_64-w64-mingw32 ./waf configure
./waf build
