DESCRIPTION
       access()  checks whether the process would be allowed to read, write or
       test for existence of the file (or other file system object) whose name
       is  pathname.   If  pathname is a symbolic link permissions of the file
       referred to by this symbolic link are tested. [...]

       Only  access  bits  are checked, not the file type or contents. [...]

       If  the process has appropriate privileges, an implementation may indi-
       cate success for X_OK even if none of the execute file permission  bits
       are set.

Note "or other file system object."
