C string literal storage between multiple copies of a process or library

Question

What is the behavior of various systems when you have more than one copy of a specific program or library, do string literals run once in RAM or once for each copy of a process / library? What if they are stored in an array like:

static const char *const foo[] = { "bar", "baz", "buz" };

Does behavior staticchange memory behavior?

Edit: since this is probably platform specific, what is the behavior of the Microsoft compiler on Windows or the GCC on Linux (x86)?
