Created attachment 29064
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=29064
Minimal test case

The attached test case illustrates the problem.  When compiled with -Wall
-Wextra -Werror, it reports:

  bug55830.c:6:44: warning: 'bar' defined but not used

However, it does not report a similar warning for 'foo'.
