Just what makes an architecture "C Friendly"?

As if the subject didn't give it away already, I'd like to point out
that I am merely an interested amateur when it comes to embedded
issues. My apologies if this question is OT.

Reading the interesting thread on "What's wrong with a PIC", I noticed
a lot of comments regarding the C friendly/unfriendly architectures of
various micros.

So, the question - what makes an architecture C friendly? Also, what
are the other merits/demerits (C apart) of the various architectures?

Thanks,
Mike
