What's the difference between arch-specific header files of uClib and those header files of linux kernel

[Ahan Hsieh 謝武漢]

Dear all,

Now, I want to port uClibc to a new architecture. 
And I have already port uCliunx to this architecture.

When I port uClibc to this new architecture, I got a trouble.

Take fcntl.h as an example:
In uClibc/libc/sysdeps/linux/ARCH/bits/fcntl.h of uClibc, 
there is also a fcntl.h in linux-2.6.x/include/asm-ARCH/fcntl.h of linux 
kernel.

I traced some architectures' (such as mips, arm, ...) source, 
these architectures owns a fcntl.h in 
uClibc/libc/sysdeps/linux/ARCH/bits/fcntl.h of uClibc,
and is different from linux-2.6.x/include/asm-ARCH/fcntl.h of linux kernel 
?

Why don't they use the sam fcntl.h ?

If one day, the architecture some macro's definition of linux kernel, 
dose macro's definition of uClibc need to be modified?

Best regards,
