Contrary to what POSIX says, some directory operations on MacOS can fail
with EPERM instead of EACCES, so we need to handle both.
libstdc++-v3/ChangeLog:
PR libstdc++/99537
* src/c++17/fs_dir.cc (recursive_directory_iterator): Use new
helper function to check for permission denied errors.
* src/filesystem/dir.cc (recursive_directory_iterator):
Likewise.
* src/filesystem/dir-common.h (is_permission_denied_error): New
helper function.
Tested powerpc64le-linux. Committed to trunk.

Oh drat, that's the wrong PR number. It should be PR 99533, as the
comment says in the code. I'll fix the ChangeLog tomorrow.
