Knowing what a compiler does is basic knowledge. Knowing how to invoke a specific one from a command line is a matter of culture. It's like the difference between knowing the physics of baseball and the rules of baseball.

You'd probably be better off giving someone the binaries for a broken hello-world and asking them to debug it.
