我用make命令编译sqlte时为什么会出现这种错误啊 ：
nios2-elf-gcc -g -DOS_UNIX=1 -I. -I./src -DNDEBUG -DTHREADSAFE=0 -DSQLITE_THREA
D_OVERRIDE_LOCK=-1 -DSQLITE_OMIT_LOAD_EXTENSION=1 -c ./src/vdbe.c -DPIC -o .lib
s/vdbe.o
./src/vdbe.c: In function `sqlite3VdbeExec':
./src/vdbe.c:1289: error: duplicate case value
./src/vdbe.c:877: error: previously used here

./src/vdbe.c:1716: error: duplicate case value
./src/vdbe.c:1086: error: previously used here 是不是与configure后面的host的参数有关系啊。
运行configure时，曾经出现过下面的错误
#../configure --prefix=/usr/sqlite/sqlite-pc/ --host=
$ARCH-uclinux
configure: WARNING: If you wanted to set the --build type, don't use --host.
If a cross compiler is detected then cross compile mode will be used.
checking build system type... i686-pc-cygwin
checking host system type... configure: error: /bin/bash ../config.sub -uclinux
failed 我不知道怎么改，就去掉了configure后面所有参数，运行configure完后，编译make后就出现上面的错误。我用的是nios2linux1.4操作系统，nios2软核cpu。host是什么参数，怎样设置？？？
