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.

------------------BEGIN foo.c---------------
typedef struct
{
    int a;
} *foo_ptype;

void main(int argc, char* argv[])
{

    foo_ptype foo, *bar;
    foo = 0;
}
