With some "old" toolchains (glibc, uclibc in version 4.9.4, 5.3, 5.4,
5.5 ...), the following error is raised by the compiler:
../src/screen.cxx:60:29: required from here
/usr/lfs/v0/rc-buildroot-test/scripts/instance-1/output/host/opt/ext-toolchain/mips-linux-gnu/include/c++/5.3.0/ext/new_allocator.h:120:4:
error: no matching function for call to 'std::pair<const screen_functions* const, std::unique_ptr<Page> >::pair(const screen_functions*, Page*)'

/usr/lfs/v0/rc-buildroot-test/scripts/instance-1/output/host/opt/ext-toolchain/mips-linux-gnu/include/c++/5.3.0/bits/stl_pair.h:112:26:

/usr/lfs/v0/rc-buildroot-test/scripts/instance-1/output/host/opt/ext-toolchain/mips-linux-gnu/include/c++/5.3.0/bits/stl_pair.h:112:26:
note: no known conversion for argument 2 from 'Page*' to 'const std::unique_ptr<Page>&'
This is due to the fact that init function of screen_functions
structure returns Page* but PageMap wants a std::unique_ptr<Page>
To fix this, cast raw pointer into a unique_ptr with an explicit cast
