Compile FastBoot (used for android user space flashing) on Windows

I have compiled FastBoot on Linux platform. But I am stucked while compile it on windows.I am using WinDDK for compilation of FastBoot on windows.In WinDDK, It is giving errors like 开发者_StackOverflow中文版missing "unistd.h","sys/time.h","zipfile/zipfile.h".

Are there any replacement files for above said in windows?.Please suggest if any suitable method to port the code from linux to Windows environment.

Header file unistd.h is available only on POSIX systems. Fastboot on Windows can be compiled using Cygwin.
