Description
Trying to build MuseScore using Qt 5.15.0 snapshot, and now alpha, under Windows using MSVC 2017 (haven't tried MinGW yet) gives lots of compiler errors like the following (sorry, some parts in German):
C:\Qt\5.15.0\msvc2017_64\include\QtCore/qmap.h(1213): error C2244: "QMultiMap<K,V>::insert": Keine Übereinstimmung für Funktionsdefinition mit vorhandener Deklaration gefunden [...\msvc.build_x64\audiofile\audiofile.vcxproj] C:\Qt\5.15.0\msvc2017_64\include\QtCore/qmap.h(1211): note: Siehe Deklaration von "QMultiMap<K,V>::insert" C:\Qt\5.15.0\msvc2017_64\include\QtCore/qmap.h(1213): note: Definition C:\Qt\5.15.0\msvc2017_64\include\QtCore/qmap.h(1213): note: 'QMultiMap<K,V>::iterator QMultiMap<K,V>::insert(const Key &,const T &)' C:\Qt\5.15.0\msvc2017_64\include\QtCore/qmap.h(1213): note: Vorhandene Deklarationen C:\Qt\5.15.0\msvc2017_64\include\QtCore/qmap.h(1213): note: 'QMap<K,V>::iterator QMultiMap<K,V>::insert(QMap<K,V>::const_iterator,const Key &,const T &)' C:\Qt\5.15.0\msvc2017_64\include\QtCore/qmap.h(1213): note: 'QMap<K,V>::iterator QMultiMap<K,V>::insert(const Key &,const T &)'

Same code builds just fine using Qt 5.12.6 and 5.9.x
