bug-153965.c:6: warning: control reaches end of non-void function
^^^
$ gcc-3.2 -Wall -c bug-153965.c

bug-153965.c: In function `foo':
bug-153965.c:13: warning: control reaches end of non-void function
^^^^^
gcc 3.[23] also produces correct line numbers if either "static" or
"inline" is removed from foo. Removing the body of function foo()
causes a secondary warning to be generated in the right place, but the
original warning still has the wrong line number.
