Spurious "file errors" when making master

[martin rudalics]

I recently get spurious "file errors" when building master.  The first one
is from Windows XP and goes as

>>Error occurred processing ../../lisp/gnus/gnus-group.el: File error (("Renaming" "Permission 
denied" "c:/emacs-git/trunk/lisp/gnus/gnus-group.elc2552Dme" 
"c:/emacs-git/trunk/lisp/gnus/gnus-group.elc"))

That file still has its extension .elc2552Dme.

The second one is from Debian and goes as

Error running git rev-parse: (file-error "Searching for program" "No such file or 
directory" "git")

Any ideas?

Thanks, martin
