    libstdc++: Fix test for libstdc++ not including <unistd.h> [PR100117]

    The <cxxx> headers for the C library are not under our control, so we
    can't prevent them from including <unistd.h>. Change the PR 49745 test
    to only include the C++ library headers, not the <cxxx> ones.

    To ensure <bits/stdc++.h> isn't included automatically we need to use
    no_pch to disable PCH.

    libstdc++-v3/ChangeLog:

            PR libstdc++/100117
            * testsuite/17_intro/headers/c++1998/49745.cc: Explicitly list
            all C++ headers instead of including <bits/stdc++.h>
