Here are the build scripts for my MinGW distro.

You'll need to run them in MSYS2, which you can set up without an installer:

• Go to: http://sourceforge.net/projects/msys2/files/Base/x86_64/
• Download the most recent version of: msys2-base-x86_64-20150916.tar.xz
• Extract it to: C:\Temp\gcc\msys64
• Run: msys2_shell.bat
• CLOSE MSYS2 BY CLICKING THE WINDOW'S RED X. (Don't type exit.) Restart MSYS2.
• In MSYS2, run: update-core
• CLOSE MSYS2 BY CLICKING THE WINDOW'S RED X. (Don't type exit.) Restart MSYS2.
• In MSYS2, run: pacman -Su cmake diffutils make nasm patch tar texinfo

The build scripts assume that they can use C:\Temp\gcc as a working directory and that they do not live directly within it. They also assume that they live next to the sources. I generally put both of them into C:\Temp\gcc\sources-VERSION .

I highly recommend that you execute each build script by hand before attempting to run it in one shot.
