Control Flow Guard (CFG/CFGuard) for mingw-w64

Control Flow Guard is a security mitigation that verifies the target address of indirect calls. It works by having the compiler insert a check at indirect call sites to verify the validity of the call target, and also the linker write the necessary data and flags into the PE/COFF image to enable the feature on Windows' end.

The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)
