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 (...)).
