dirname.h is proving quite useful from multiple LGPL modules,
given the number of trailing slash bugs fixed in syscalls;
only the calls to xalloc_die need to remain GPL.

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/dirname (Files): Remove m4/double-slash-root.m4.
(Depends-on): Add double-slash-root.
