I think the ifdef needs to remain so that both next and master branch can be fuzzed

Oh I found both master and next branch has the same CS_NEXT_VERSION = 5, that's why I removed it.

Ok thanks @david942j so your code is good

@aquynh how can a program know at compile time which architectures are supported by the current capstone ie branch master and branch next ?

Great !

Cheers @david942j
PS : if you know about BPF, could you take a look at the-tcpdump-group/libpcap#777
