Don't call them. Raise a stink. Really.

In the meantime write wrappers for these functions, in the wrappers call, check the implicit variables, and return them. Then when the code can be fixed, less has to be changed. If you can, localize the variables in your wrapper.

And "use strict" to be sure you have everything lexically scoped.

But people like that are a hazard to your code base, nothing more and nothing less.
