MacOS X 10.7 added an fdatasync syscall and exports a symbol for it, but fails to declare it anywhere. Lacking any hard evidence that this syscall is broken, we will just provide the declaration and use it. * m4/fdatasync.m4 (gl_FUNC_FDATASYNC): Check for present but not declared. * m4/unistd_h.m4 (gl_UNISTD_H_DEFAULTS): Another default. * modules/unistd (Makefile.am): Substitute it. * lib/unistd.in.h (fdatasync): Declare on MacOS. * doc/posix-functions/fdatasync.texi (fdatasync): Document it.
