Yes, GNustep does, and Cocoa does, and OpenStep does - but your basic
bog-standard Objective-C language as provided by GCC doesnt, because all
those things are libraries on top of Obj-C.

Weel, yes, also true - but GCC lets you attach a class to it as a shortcut
using the -fconstant-string-class option. So in my Makefiles I
have to have -fconstant-string-class=PFConstantString and then define
PFConstantString to be a subclass of PfString, and have no-ops for retain,
release and the rest.
It works well, though the fact that the compiler knows how to lay out
the object on the stack is a bit of a pain. If you want to define a superclass
for it then you have to be careful. I just went for some ugly hackery,
but it works nicely.
