Compiling emacs from sources

[Matthias Pfeifer]

Im trying to compile emacs from sources. "git status" says there are no
changes in my working directory (compared to master branch) and I call
"./configure" and "make". make terminates with following last lines

[SNIP]
Loading register...
Loading textmodes/paragraphs...
Loading progmodes/prog-mode...
Loading emacs-lisp/lisp-mode...
Loading progmodes/elisp-mode...
Symbol's function definition is void: cl-old-struct-compat-mode
make[1]: *** [emacs] Fehler 255
make[1]: Verzeichnis »/home/matthias/emacs/src« wird verlassen
make: *** [src] Fehler 2

I don't think that something serious is going on since i keep having this
for a while (pulling in changes from the git repository but the error
remains). If I would be pointed to a solution that would be nice...
