// error: 'int truncate' redeclared as different kind of symbol

// This tests that no libstdc++ headers include <unistd.h>.
// However, as discussed in PR libstdc++/100117 we cannot guarantee that
// no libc headers include it indirectly, so only include the C++ headers.
// That means we can't use <bits/stdc++.h> because that includes <cstdio> etc.
// so we list the C++ headers explicitly here. This list is unfortunately
// doomed to get out of date as new headers are added to the library.
