I cannot seem to make it to work.  Here's what I did:

  ./src/emacs -Q
  C-x C-f src/xdisp.c RET
  move to a place that references set_cursor_from_row
  M-x xref-find-references RET

I get "Symbol's function definition is void: mapcan".

I then manually load cl, and re-invoke the command.  The result now is
"No known references for: set_cursor_from_row".  But the shell command
"gid set_cursor_from_row" returns this list of matches:

  src/xdisp.c:174:   latter, see also set_cursor_from_row).
  src/xdisp.c:380:   cursor; <= 0 if not known.  Set by set_cursor_from_row, used for

  src/xdisp.c:4421:                 text, which confuses `set_cursor_from_row'.

In case it matters, the ID file was produced manually with this
command in the top-level Emacs directory:

  mkid -o ID .

What am I missing?
