How to change and save a read-only file?

Hi,

I often would like to edit files in emacs, which are write-protected
(owned by root, for example). With "C-x C-q" I can disable 'read-only
mode', which allows me to make changes in the file. But when I want to
save the file, I obtain "File ... is write-protected; try to save
anyway? (y or n)". Even if I choose 'y', it fails (*Messages* saying:
"basic-save-buffer-2: Doing chmod: operation not permitted").

What's the 'correct' approach to easily edit (change + save) such files?

Cheers,

Marius
