From 29ec33360da9171f1df27ef59ea4576fda4065ff Mon Sep 17 00:00:00 2001 From: Corinna Vinschen Date: Fri, 19 Jan 2024 11:20:17 +0100 Subject: 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.
