The same problem happens in emacs-21.3-25.src.rpm, too.
That's a bug in emacs. POSIX allows getcwd (actually, most of its functions) to be also defined as function-like macros. If emacs wants to use getcwd for something else, it should either #undef getcwd first or prevent its expansion as function-like macro (e.g. using (getcwd) (...) instead of getcwd (...)).
