* .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.
