Description
When building qt from source I get following error:
dwojt@debian:~/local/qt5$ ~/sources/external/qt5/configure -developer-build -opensource -confirm-license -nomake examples -nomake tests
(...)
dwojt@debian:~/local/qt5$ make
In file included from /usr/include/c++/9/memory:67,
from .moc/moc_qabstractgallery.cpp:9,
from /home/dwojt/sources/external/qt5/qtdocgallery/src/gallery/qabstractgallery.cpp:125:
/usr/include/c++/9/bits/stl_raw_storage_iter.h:69:22: error: expected template-name before '<' token

When investigating contents of qabstractgallery.cpp, I found that "moc_qabstractgallery.cpp" is included from within QT_{BEGIN|END}_NAMESPACE_DOCGALLERY .
Then moc_qabstractgallery.cpp includes "<memory>". Effectively "<memory>" gets included from namespace "QDocGallery".
Adding "#include <memory>" before QT_BEGIN_NAMESPACE_DOCGALLERY allows compilation of this file to succeed, which confirms my diagnosis.
Please prevent system includes from being included from inside a namespace.
