the reason you're getting the compile link failure is because on windows, we
build a dll that has a little bit of chrome (see the chrome_dll_nacl_win64
target) in 64 bits for the nacl sandbox to work.  it doesn't link in with
webkit/skia etc, since those aren't built in 64 bit (and we wouldn't want them
to, since it would bloat the binary unnecessarily).

one (admittedly hacky) way to get around this would be to surround the body of
these functions with "#if !defined(NACL_WIN64)", similar to other places in this
file

Thanks.   (Fixed in render_messages.h, as you saw.)
