STEP BY STEP INSTALLATION GUIDE:

Step 1:

Get Cygwin:

32-Bit: https://cygwin.com/setup-x86.exe
64-Bit: https://cygwin.com/setup-x86_64.exe

Note: You can compile for 64-bit in a 32-bit environment.

Click on setup-*.exe and install the following packages:

git, make, clang, gcc-core, gcc-objc, gcc-g++,
patch, wget, libuuid-devel, openssl and pkg-config

For LTO support you will also need:

libllvm-devel, libllvm, libedit and libffi
