Unfortunately, the patch breaks Solaris 10 bootstrap, which lacks
fchmodat:

/vol/gcc/src/hg/trunk/local/libstdc++-v3/src/filesystem/ops.cc: In function 'void std::experimental::filesystem::v1::permissions(const std::experimental::filesystem::v1::__cxx11::path&, std::experimental::filesystem::v1::perms, std::error_code&)':
/vol/gcc/src/hg/trunk/local/libstdc++-v3/src/filesystem/ops.cc:890:17: error: '::fchmodat' has not been declared
   if (int err = ::fchmodat(AT_FDCWD, p.c_str(), static_cast<mode_t>(prms), 0))
                 ^
make[6]: *** [ops.lo] Error 1
