Well. I have reverted the change of `tramp-drop-volume-letter' to the
definition as it has been before the change in #105625. Compiled
tramp.el and tramp-sh.el on GNU/Linux. Copied the resulting tramp.elc
and tramp-sh.elc into the Emacs 24.3 tree on MS Windows. The problem
persists.

I have the impression, that there is a byte-compiler optimization, which
throws away the call of `tramp-drop-volume-letter' in
`tramp-sh-handle-expand-file-name'. As I have said earlier,
(tramp-drop-volume-letter "c:/something") still works correctly.

How could I avoid this eager optimization?

Best regards, Michael.
