有以下两种解决办法：
1)进入到build_dir/host/m4-1.4.15/lib目录，更改stdio.in.h
#undef gets
#define gets(a) fgets( a, sizeof(*(a)), stdin)
2)可以使用以下命令
cd /home/openwrt-dreambox/build_dir/host/m4-1.4.15/lib
sed -i -e '/gets is a security/d' ./stdio.in.h
即可编译通过。
在另外在编localcharset.c 时出会出现类似的问题，同样是进入到build_dir/host/bison-2.4.3/lib
cd /home/openwrt-dreambox/build_dir/host/bison-2.4.3/lib
sed -i -e '/gets is a security/d' ./stdio.in.h
即可编译通过
