No, I did it to inline them for the optimized build.  I'd assumed
that methods defined in header files like that would be inlined,
but they don't seem to be.  Maybe this is a peculiarity of the
IcedTea build, which is where I noticed the problem.  If it is,
I can remove it from this webrev.

Basically because I didn't know if I'd need to make changes anywhere
else, and I didn't want to break the other platforms.  Should I change
it to what the comment says?
