Hmm, that's funny. I thought PDNS is using threads. But you may be right that 
the pthread_self function may be overwritten. I simply don't know, what 
extern "C" is really doing if you supply a function with a body.

Yes, that's not the most portable way, but it is ok in this case because 
pthread_t is a long integer if I remember correctly. Before we are arguing 
about the cast, it would be better to know what the "extern" thing is really 
doing.
