STEP 1: Create cscope xref

$ cd ~/src/emacs/trunk/src (This is a Bzr checkout)
$ find . -name '*.[ch]' > cscope.files
$ cscope -b

$ ls -al cscope.*
-rw-r--r-- 1 kjambunathan kjambunathan    2159 May 24 00:20 cscope.files
-rw-r--r-- 1 kjambunathan kjambunathan 8346136 May 24 00:20 cscope.out

STEP 2: Enable semantic

emacs -Q

Tools->Source code parsers(Semantic)->ON

STEP 3: Visit some C file in Emacs src.  Make sure cscope is used as symref tool

C-x C-f ~/src/emacs/trunk/src/buffer.c

STEP 4: Lookup definition of `set_interval_object'

C-c , J 

The above command would have loaded symref tool.  Make sure cscope
(and not grep) is the one that is used.

M-: (semantic-symref-calculate-rootdir)
    => "/home/kjambunathan/src/emacs/trunk/src/"

M-: (semantic-symref-detect-symref-tool)
    => cscope

STEP 5: Position the cursor over `INTERVAL' in it's signature

static void
set_interval_object (INTERVAL i, Lisp_Object obj)
C-c , J

STEP 6: Expected Behaviour

I expect that 'INTTERVAL' be offered at the prompt.  Note the bug. `INTERVAL' 
is a symbol right.

Just type INTERVAL out.  Now semantic refuses to proceed ahead saying no match.

STEP 7:  Check that the native cscope looks up INTERVAL just fine.

$ cscope
$ C-n (Cursor should be in Find this global definition)
$ Type out INTERVAL

cscope will take you to lisp.h with cursor at

     typedef struct interval *INTERVAL;

STEP 8: Can semantic do the right thing when I lookup INTERVAL?

I have a local fix that works for me.  So closing it.
