Richard,

The comment at DO_STMT led me to believe that DO_BODY was the first operand.

cp-tree.def:
...
./* Used to represent a 'do' statement. The operands are DO_BODY and
   DO_COND, respectively.  */
DEFTREECODE (DO_STMT, "do_stmt", tcc_statement, 2)
..

However, in cp-tree.h we see that DO_BODY is actually the second operand:
...
/* DO_STMT accessors. These give access to the condition of the do
   statement and the body of the do statement, respectively.  */
#define DO_COND(NODE)		TREE_OPERAND (DO_STMT_CHECK (NODE), 0)
#define DO_BODY(NODE)		TREE_OPERAND (DO_STMT_CHECK (NODE), 1)
...

The patch fixes the comment.

OK for trunk?

Thanks,
- Tom
