The devs have been thinking about removing the class, but they couldn't
do it due to bugs in GCC 9 and 10, apparently: https://bugreports.qt.io/
browse/QTBUG-117850 <https://bugreports.qt.io/browse/QTBUG-117850>. They
are preparing the code base for its removal, it seems: https://
codereview.qt-project.org/c/qt/qtbase/+/192881 <https://codereview.qt-
project.org/c/qt/qtbase/+/192881>.

From what I see, the issue is with i686 (32 bits) compiler mingw-w64.
Enrico, is this thing relevant these days? In particular, can a newer
fixed compiler be used for the old targets with a 32 bits architecture ?
Note also that the issue is only for types that need a destructor, if I
read correctly the bug report. And indeed the warning says
"QThreadStorage used with a trivial non-pointer type; consider using
thread_local".
As a first step, I'll try to remove these calls (but I'll have delays
to do so). It should be enough to replace the "static
QThreadStorage<int>" by "thread_local static int".
Yes, I think it is the way to go.
