Bug 203747

Description of problem:

Using emacs and etags for kernel (and other) development, the search to find a
macro definition doesn't work.  When I put the cursor on a macro, and hit M-. to
find where it is defined, it gives me just another instance of the macro. I can
repeat the search (C-u M-.) serveral times and it will evetually get to the
definition (but not always).  I do not have this problem on Debian Testing,
where there it gives me the macro definition the first time, everytime.

Version-Release number of selected component (if applicable):

$ emacs --version

How reproducible:

everytime I do a macro search on a Linux kernel or Xen tree.

Steps to Reproduce:
1. find . -name '*.[ch]' | xargs etags # done in a Xen or Linux Kernel tree, and
yes this also works with a "make TAGS" in a Linux kernel.
2. Start emacs on some C file with macros
3. Place cursor on a macro (where there are lots of instances of it).
4. Hit M-. (will need to also load the TAGS file).

Then it takes you to another instance of the macro instead of the defined.

  
Actual results:

Brought to another instance of the requested macro.

Expected results:

Brought to the definition of the macro.
