Yeah, it's annoying, but that often happens. One has to be careful to
check though - the wince stuff is usually just a subset of the full

always making sure you look at the win32 docs, not wince.

Right.

Ok, I've applied a patch that does this. Given that it's certainly not
in a performance critical path, the overhead shouldn't be noticeable,
and it's certainly not wrong to do it :)
