ORIENT: avoid "expression has no effect" warning
The warning "right-hand operand of comma expression has no effect [-Wunused-value]" crops up with -Wall in cases where ORIENT is called without checking or assigning its value. Explicitely void the expression in these cases to avoid the warning. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
