* etags.el (tag-lines-already-matched): Remove defvar.
(initialize-new-tags-table): Don't make that var local.
(tag-lines-already-matched): Add docless defvar near find-tag-in-order
defun; this is a global state variable for that one function.
(find-tag-in-order): Move clearing of tag-lines-already-matched out of
loop. Make it a list of markers and search it with member; it is now
global, not buffer-local in the tags table, and records all matches in
any tags table during a single find-tag loop. When we run out of
matches, clear it and null out the markers.

here if not yet done.

which is valid on MS-DOS.
(c-macro-expansion): Do not rely on ``/tmp/'' being present; use
environment variables as alternatives (MSDOS). Use
`shell-file-name' rather than ``sh''. Redirect `stderr' with
`call-process-region' option, not from the shell. Handle shells
which don't return exit code from `cpp' (MSDOS). Put messages
from `cpp' inside a comment, to avoid messing up syntax highlighting.
