First, you will need to install the following packages using the Cygwin installer:
- make
- gcc-g++
- bison
- flex
- texinfo
- binutils (Make sure to check the "Src?" checkbox since we're interested in the source code. Once the download is finished, you will find it in `/usr/src/`)
Add the new binutils binaries to your system PATH:
You can do that by adding `PATH=$PATH:/opt/cross/bin` to `~/.bashrc` and then reloading `~/.bashrc`.
Alternatively you can edit the `Path` variable in `Edit the system environment variables`>`Environment Variables` (in which case you will need to relaunch your terminal).
