Dimitry, are you talking about case lib.atf.libatf-c++.atf_c++_test.include=
 ?

I happen to have a r304986 VM here:

https://people.freebsd.org/~lwhsu/tmp/disk-test.img.xz

(it starts kyua test in /etc/rc.local, just use ctrl-c to interrupt it)

And there is a /usr/include/c++/v1 directory with sstream in it.


BTW, I am not sure removing -I/usr/include is the right solution,  I
think this case is checking for "normal" compiling would work, not
during buildworld.  When this case was passing, it uses following
command:

c++ -O2 -pipe -DHAVE_CONFIG_H -I/usr/include -Wall -Werror -o test.o -c tes=
t.cpp

and now it uses:

c++ -target x86_64-unknown-freebsd12.0 --sysroot=3D/usr/obj/usr/src/tmp -B/=
usr/obj/usr/src/tmp/usr/bin -O2 -pipe -DHAVE_CONFIG_H -I/usr/include -Wall =
-Werror -o test.o -c test.cpp

This changed between r304555 and r304698.


Also, does anyone know where is "-I/usr/include" coming from?  Is this
one?
