I was looking for a similar thing a while back.  One great tool for
 navigating the wine source is the etags program.  In the wine source
 directory, type 'make etags'.  This makes a file called TAGS.  Then, start
 emacs, and type alt-x visit-tags-table, and load the tags file.  You can
 navigate the source by function.  See the tags manpage and the emacs
 manpage for the tags section for details.
