Any QList<custom type> requires this on MSVC, right? Then I would strongly suggest a solution within Qt itself, <em style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">if</em> a central solution such as a macro is indeed needed. But thinking about it, a one-line dummy impl that returns 0 doesn't really seem worth a macro to me.
I.e. why not do like qitemselectionmodel.h does, everywhere where this is needed?</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">But I am still surprised that Qt only needs this in qitemselectionmodel.h
Take this for instance:
src/corelib/io/qstorageinfo.h: static QList<QStorageInfo> mountedVolumes();
Why doesn't this require a qHash(QStorageInfo)?
If I explicitly call toSet() on such a list, I do get a compile error (on Linux) due to the missing qHash implementation. http://www.davidfaure.fr/2015/storageview.diff
So MSVC doesn't <em style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">always</em> instanciate the toSet() method, but only in some cases?
Or are we looking at an old MSVC issue which doesn't exist anymore with more recent MSVC versions? i.e. did you try removing this block (in konq_historyentry.h) altogether to check it's still needed?</p></pre>

MSVC 2013 still has the same beahviour.</pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Sounds to me like further research is needed, I don't like fixes where we don't really understand what's going on.</p></pre>
