Having nested function is irrelevant to being object-oriented.

C# doesn’t have nested functions, but you can use lambdas (See Why doesn't C# have lexically nested functions?). So are all other programming languages that support anonymous functions (including C++0x).
You may create a local class, and overload the call operator to simulate a nested function (See is it possible in C or C++ to create a function inside another?).
Meanwhile, many non-object-oriented languages like (the original) Pascal support nested functions natively, and GCC support it in C as an extension.
