I can confirm that this bug is still in Emacs. The problem is this regexp:
(defvar makefile-dependency-regex
;; Allow for two nested levels $(v1:$(v2:$(v3:a=3Db)=3Dc)=3Dd)
"^\\(\\(?:\\$\\(?:[({]\\(?:\\$\\(?:[({]\\(?:\\$\\(?:[^({]\\|.[^\n$#})]+?[=
})]\\)\\|[^\n$#)}]\\)+?[})]\\|[^({]\\)\\|[^\n$#)}]\\)+?[})]\\|[^({]\\)\\|[^=
\n$#:=3D]\\)+?\\)\\(:\\)\\(?:[ \t]*$\\|[^=3D\n]\\(?:[^#\n]*?;[ \t]*\\(.+\\)=
\\)?\\)"
"Regex used to find dependency lines in a makefile.")
Of which I can only say... "eek".
I wonder -- has anybody considered rewriting make-mode.el using
syntax-ppss? Or is the syntax just too intractable for that?
