Can we please get the ifdefs tided up before this goes in.

For the moment this has a NAK from the tty maintainer but if the ifdefs
turned went into headers where they belong and the code looked like say

		tc = vc_translate(vc, c);

with two versions of vc_translate (one being vc_translate(x) (x)) it
might be more reasonable.

We can't stick random ifdefs in bits of code for arbitary 6K savings or
the entire kernel would be ifdefs.


Sor for the moment
