* lib/dirname.h (DOUBLE_SLASH_IS_DISTINCT_ROOT): Default to 0, not 1. This is more consistent with the other defines here. * m4/double-slash-root.m4 (gl_DOUBLE_SLASH_ROOT): Port to z/OS. Problem reported by Paul Gilmartin. Change local vars to use gl_ prefix rather than ac_. Don't define DOUBLE_SLASH_IS_DISTINCT_ROOT to 0, for consistency with other defines. * modules/double-slash-root: New module. * modules/dirname (Files): Remove m4/double-slash-root.m4. (Depends-on): Add double-slash-root. * MODULES.html.sh (File system functions): Mention new module.
