From 20803d7881c3865edede170579f55261140b5d0d Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Thu, 7 Nov 2013 19:07:38 -0500 Subject: [PATCH] Make LOCK_PRINT & PROCLOCK_PRINT expand to ((void) 0) when not in use. This avoids warnings from more-anal-than-average compilers, and might prevent hidden syntax problems in the future.
