It's quite clear. No problem. I was just a little bit nerved.

MTD is just following the ongoing kernel development. 2.4.18 is an "ancient" 
kernel and has several functions / macros not implemented. You can either 
backport those functions or use 2.4.21.

Why don't you want to use 2.4.21 ?

By specifying 2.4.18 you are explicitly saying you _want_ to use old
broken code and you don't want bug-fixes. So just use the MTD code that
is _in_ 2.4.18. Or upgrade your kernel.
