I was thinking primarily of the fact that anytime the C compiler 
changes anything about its ABI, the C++ compiler needs to know about 
it and take steps to compensate. Fortunately, at least in most cases 
the ABI is fairly stable, so this doesn't arise a lot in practice.

In practice, it's likely to work at least as long as none of the 
functions is virtual. A virtual function would stand a good chance of 
causing breakage though...

I haven't studied that in a lot of detail yet, but it looks like 
there's a fair bit of new material to study. First of all, they've 
added thread local storage, and associated initialization rules for 
it. Then they've added constexpr's, which allow static initialization 
in quite a few cases that it wouldn't work in C++ 98/03.

Those have caused enough changes to the text that I haven't yet 
sorted out whether the underlying rules have changed a lot, or 
whether it's mostly just different text describing mostly similar 
rules with a couple of new possibilities thrown into the mix.
