which is nearly OK(?), there are hard-coded /usr/local/include and
/usr/include,
not sure why.
The behavior possibly depends on the configuration, mine is just all defaults.
Even the standard openSUSE packages work the same, with the exception of
/usr/local/include and /usr/include again:

So can you please, instead of using Ubuntu packages, build GCC yourself so you
can report from unpatched GCC sources and with the exact configury you used?
