>Description:
When defining a function inline in a class and no returnvalue is given, 
while
it should not be void, there is no warning, not even with -Wall.

>How-To-Repeat:
compile this:

class foo
{
public:
  int bar ()
  {
  }
};

int main ()
{
  foo f;
  f.bar ();
  return 0;
}

with g++ -Wall -Wshadow -ansi -O5 -ggdb3 bug.cc
and see no warnings
>Fix:
a workaround obviously is to give a returnvalue. However finding such an
error is not easy without the warning, especially because it is expected.
