Normally I'd agree, but in this case it might be worth it... for windows ce specifically, jeff muizelaar wrote a decompiler a while ago that could generate msvc assembly from compiled gcc code, which seemed to be a good way to go.  MSVC doesn't do inline assembly on ARM anyway, so it would need to be done either way.
