 2011-01-09  Paul Eggert  <eggert@cs.ucla.edu>
 
+        Include <unistd.h> unilaterally.
+        * emacsclient.c, etags.c, fakemail.c, make-docfile.c, movemail.c:
+        * pop.c, test-distrib.c, update-game-score.c:
+        Include <unistd.h> without worrying about HAVE_UNISTD_H, since
+        unistd.h is always present now, possibly supplied by gnulib.
+
         Include <getopt.h> not "getopt.h".
         * ebrowse.c, emacsclient.c: Include <getopt.h>, not "getopt.h".
         Since getopt.h is no longer in this directory, there's no point
