ORIENT: avoid "expression has no effect" warning

Browse Source 
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.
