[Spot] Bug in version 2.8.6

Hi Spot Team,

I am trying to compile Cyclist (cyclist-prover.org) against the latest 
version (2.8.6) of Spot, and I am getting an error.

Cyclist is including spot/twa/twa.hh, and when compiling I get the 
following error:

In file included from 
                  from src/soundness/proof_aut.hpp:4,
                  from src/soundness/proof_aut.c:1:
In constructor ‘spot::bitset<N>::bitset(spot::bitset<N>::word_t)’:
error: constexpr constructor does not have empty body

In fact, I also get this error when trying to compile again versions 
2.6.3 and 2.7.5 too.

When I try to compile against version 2.5.3, I get the error that there 
is no such file spot/twa/twa.hh.

Is this a bug, or has the API changed? If the latter, how should I 
update my code to use the newer versions?
