Ok, sorry, the previous email was wrong: I was looking at a too old version
of CFFI. In the recent versions the code looks fine
#+long-long
(:long-long :long-long "long long")
#+long-long
(:unsigned-long-long :unsigned-long-long "unsigned long long")
but there is a line at the beginning disabling long-long
(pushnew 'no-long-long *features*)
I will investigate this further.
