commit 00510919993da49cf91421fe13242a7d8a82c1fd Author: Corinna Vinschen <[email protected]> AuthorDate: Wed Jul 12 13:45:24 2023 +0200 Commit: Corinna Vinschen <[email protected]> CommitDate: Wed Jul 26 15:14:27 2023 +0200 Cygwin: use new _AT_NULL_PATHNAME_ALLOWED flag Convert gen_full_path_at to take flag values from the caller, rather than just a bool indicating that empty paths are allowed. This is in preparation of a better AT_EMPTY_PATH handling in a followup patch.
