Sorry I do not understand what you want to say exactly here.
Are you saying that even though Peter's method is flawed and yet
it will work for OpenOCD Windows binaries and many other
Windows binaries? In that case, Peter's method is still
practical for many projects.

Are you thinking of gcc or things like that which Peter's method
may fail?
