unistd: avoid namespace pollution on non-glibc systems * lib/unistd.in.h: #define __need_getopt before including <getopt.h>. This avoids namespace pollution on non-glibc systems, by causing gnulib unistd.h to behave more like glibc unistd.h. I also hope that this fixes a bug on FreeBSD, reported by Mats Erik Andersson in <http://lists.gnu.org/archive/html/bug-gnulib/2013-02/msg00027.html>.
