Yes (in 2.0). It is done by converting the types of function parameters
into a signature "string", and appending that string to the function name.
If the function parameter types don't line up across object files, the
linker won't match up the names and will issue error messages.

Note that variables and function return types are not included in this scheme.

Bjarne Stroustrup presented a paper on this at the Denver Usenix C++ conference.
