Description of problem:
The renaming doesn't seem to do anything. When I try to refactor a function, I
get the renaming dialog, then when I click 'Preview' it says that the
refactoring doesn't seem to affect any code, and doesn't rename the function.

Version-Release number of selected component (if applicable):
eclipse-cdt-3.0.2

How reproducible:
Always.

Steps to Reproduce:
1. Create a new managed make project (C)
2. Create a .c file with a main function and another function, have main call
the other function.
3. Select the other function, choose Refactor->Rename in the menu, enter a new
name, click Perview.

  
Actual results:
Get a message saying 'The refactoring doesn't change any source code.'.

Expected results:
Refactor the damned mehotd.
