Looking at these warnings again, I think these may be hard to remove, as 
I get similar warnings when passing "TRUE" and "FALSE" as parameters to 
functions expecting bool on i386, even when I cast them to bool.

Can you try casting one of the constants to size_t and telling me 
whether this fixes it or not, and also the version of gcc you're using?

If casting fixes the problem, I'm happy to put all the relevant casts in 
(or perhaps better, use constants of the correct length). If not, I'm 
inclined to see whether gcc 4 fixes the problem, because so far I have 
benefitted enormously from all the warning settings and I am loth to 
turn them off.

You can of course set the CFLAGS for your own builds to get rid of that 
particular warning.
