gdb makes a mistake in printing "whatis" information on pointer-to-a-pointer
to a struct. To reproduce the bug, do the following:
1. gcc -g foo.c -o foo
2. gdb foo
3. break main
4. whatis foo
5. whatis bar
If you look at the gdb output to steps 4 & 5 above, they are the same.
However one is a ptr to a struct and the other is ptr-to-ptr to a struct.
