Help needed for jffs2

[yanhy at tsinghua.org.cn]

Hi,friends!I'm new to uClinux.
I am trying to port uClinx on Coldfire M5272C3.The kernel is linux-2.4.x.
Now, if i select MTD and romfs support, the kernel works well on the target.
I can see the four pre-defined flash patitions and erase them and cp files to
them.
Now,I want to use jffs1/2 .but when i select jffs1/2 support, compiling problems 
come as:
mkfs.jffs2.c:113: `__BYTE_ORDER' undeclared here (not in a function)
mkfs.jffs2.c:114: `__BYTE_ORDER' undeclared here (not in a function)
mkfs.jffs2.c: In function `create_target_filesystem':

make[2]: *** [mkfs.jffs2.o] Error 1
make[2]: Leaving directory `/user/snap-gear-uclinux/uClinux-dist/user/mt
d-utils'

What's the matter?Do i need some jffs2 patch or fix it manually?
Thanks
