It comes too late. To get LFS in explicit mode (off64_t & friends) you really
need unistd.h as the very first include. I did it for include/includes.h when
porting samba-2 to 64 bit version of ReliantUNIX:

#ifdef RELIANTUNIX
/*
 * <unistd.h> has to be included before any other to get
 * large file support on Reliant UNIX
 */
#ifdef HAVE_UNISTD_H
#include <unistd.h>
#endif
#endif /* RELIANTUNIX */

but nsswitch/wb_common.c does not include "standard" headers. Even if
wb_common.c itself does not use LFS, system headers get confused:

Compiling nsswitch/wb_common.c
/usr/include/unistd.h   288: [error]:   CFE1020 identifier "off64_t" is
undefined
  extern int ftruncate64(int, off64_t);
                              ^

etc

I once was about to change defaults to prefer 64-bit off_t instead of off64_t,
but then I spotted discussion on samba-technical that it was done
intentionally.
