[./]
* .x-sc_require_config_h: Add lib/at-func.c.
[lib/]
* at-func.c: New file, with the logic of all emulated at-functions.
* openat-priv.h: Include <errno.h> and define ENOSYS,
in support of the EXPECTED_ERRNO macro.
* openat.c (fstatat, unlinkat, fchownat): Remove function definitions.
Instead, define the appropriate symbols and include "at-func.c".
* mkdirat.c (mkdirat): Likewise.
* fchmodat.c (fchmodat): Likewise.
(ENOSYS): Remove definition.
* openat.c: Don't include <errno.h>, now that "openat-priv.h" does it.
Don't include "unistd--.h" -- it wasn't ever used.
[m4/]
* openat.m4 (gl_FUNC_OPENAT): Add at-func.c via AC_LIBSOURCES.
