+Subject: [PATCH] common: Disable enum type stream operators for Qt >= 5.14
+
+Starting from version 5.14, Qt provides stream operators for enum
+types, which collide with the ones we ship in types.h. Disable
+Quassel's stream operators when compiling against Qt 5.14 or later.
+
+(cherry-picked from 579e559a6322209df7cd51c34801fecff5fe734b)
