split off module mkdirat from module openat

[Bruno Haible]

Hi Jim,

This proposed patch splits off module mkdirat from module openat.


2011-11-04  Bruno Haible  <address@hidden>

        New module 'mkdirat', split off from module 'openat'.
        * m4/mkdirat.m4: New file. extracted from m4/openat.m4.
        * m4/openat.m4 (gl_FUNC_OPENAT): Don't require gl_SYS_STAT_H_DEFAULTS.
        Don't test for mkdirat. Don't set GNULIB_MKDIRAT, HAVE_MKDIRAT.
        * modules/mkdirat: New file, extracted from modules/openat.
        * modules/openat (Files): Remove lib/mkdirat.c.
        (Depends-on): Remove mkdir.
        (configure.ac): Remove AC_LIBOBJ of mkdirat.
        (Include): Remove <sys/stat.h>.
        * modules/mkdirat-tests: New file, extracted from modules/openat-tests.
        * modules/openat-tests (Files): Remove tests/test-mkdirat.c,
        tests/test-mkdir.h.
        (Depends-on): Remove ignore-value.
        (Makefile.am): Remove rules for test-mkdirat.
        * doc/posix-functions/mkdirat.texi: Mention module 'mkdirat' instead
        of module 'openat'.
        * NEWS: Mention the change.
