Sorry guys, I must apologise for my own stupidity...

I had an old pre-version (some years old) of the new compile.el-implementation
(without compilation-forget-errors) in my site-lisp folder which "shadowed"
the shipped one....

So, sorry for the noise - all is working fine, it was my own fault.

Ciao,
Klaus

Betreff: Re: byte-compiling an elisp-file fails in Emacs 22.1 (reproducable)
 
    Debugger entered--Lisp error: (void-function compilation-forget-errors)
      compilation-forget-errors()
      byte-compile-log-file()
      byte-compile-from-buffer(#<buffer  *Compiler Input*> "c:/home/.emacs")
      byte-compile-file("c:/home/.emacs")
      emacs-lisp-byte-compile()
      call-interactively(emacs-lisp-byte-compile)

    Even explicitly loading compile.el (which defines this function) before byte-compiling
    doesn't fix it....

That is VERY strange.  Can you check (fboundp 'compilation-forget-errors)?
