+Building LKL on Windows
+------------------------
+
+To build on Windows, certain GNU tools need to be installed. These tools can come
+from several different projects, such as cygwin, unxutils, gnu-win32 or busybox-w32. 
+Below is one minimal/modular set-up based on msys2.
+
+Common build dependencies:
+MSYS2 (provides GNU bash and many other utilities)
+https://sourceforge.net/projects/msys2/
+Extra utilities from MSYS2/pacman: 
+bc, base-devel 
+
+General considerations:
+No spaces in pathnames (source, prefix, destination,...)! 
+Make sure that all utilities are in the PATH.  
+Win64 (and MinGW 64-bit crt) is LLP64, which causes conflicts in size of "long" in the 
+Linux source. Cygwin (and msys2) are LP64, like linux. Linux (and lkl) can (currently) not 
+be built on LLP64.
+
+For MSYS2 (and Cygwin):
+Msys2 will install a gcc tool chain as part of the base-devel bundle.
+Binutils need to be re-built with patches for weak symbols as described above.
+Using the msys2 shell, cd to the lkl sources. 
+and run:
+
+    $ make tools/lkl
+
+For MinGW:
+Install mingw-w64-i686-toolchain via pacman, mingw-w64-i686-binutils need to be re-built with the 
+weak symbols patches. Start a MinGW Win32 shell (64-bit will not work, see above)
+and run:
+
+    $ make tools/lkl
+
