Ah, that's USE_THREADS not USE_ITHREADS. Ancient history. I've no idea what PERL_CAPI is. There's no reference to it in current perl headers and only a mention in Changes5.6: "Log: ensure XS_LOCKS stuff happens *before* XSUB is entered under -DPERL_CAPI" So I'll regard that as ancient history as well. As for PERL_OBJECT, I see that perl58delta.pod says "PERL_OBJECT has been completely removed." So that's yet more ancient history. So it seems that xsbypass is always enabled in 5.8+ builds. Tim.
