Include chain is ostream -> ios -> iosfwd -> bits/c++io.h -> bits/gthr.h ->
bits/gthr-default.h -> unistd.h. The same chain also includes pthread.h. These
are imported at file scope, not in namespace std, which pollutes the
application name space.
I tried to report this to libstdc++ project, but their reporting instructions
seem to lead here although strictly there's no problem with the compiler
itself.
