From bab82948507dacfff804e11e376b00d7a5e12f04 Mon Sep 17 00:00:00 2001 From: Logan Rathbone Date: Sat, 4 Feb 2023 07:51:04 -0500 Subject: Prevent ZENITY_TIMEOUT from clashing with custom response IDs Redefine ZENITY_TIMEOUT response ID as INT_MAX Also, add and use ZENITY_TIMEOUT_DEFAULT exit status (hardcoded to 5 to keep consistent with what it has happened to be for the entire 3.x release cycle; POLA and all).
