From 27b2a4a4d504d6ba06b8acd91eab17796bc3b3c8 Mon Sep 17 00:00:00 2001 From: Behdad Esfahbod Date: Thu, 19 Nov 2009 20:35:07 -0500 Subject: [PATCH] Another C++ strictness fix Pango Bug 602408 - Invalid C++ code breaks compile with Sun C++ Compiler (Error: A union member cannot have a user-defined assignment operator) According to the bug: C++ Programming Language by Bjarne Stroustrup: Chapter 10.4.12 forbids explicitly using of union members with constructors, destructors or assignment operations. So we use a set() method instead of the assignment operator. Ugly, but hey, that's life.
