I'd guess it's because of the different dependencies that are enabled. On my netbsd VM libxml2 pulls in -lpthread, for example. We add xml2's dependencies to LIBS, so if that's enabled, we end up indirectly pulling in libxml2 in as well. > > How should I have done that, by the way?

Given that linking in pthreads support fixes things, that seems the right course... I wonder if we shouldn't even be more explicit about it and just add it - who knows what extension libraries pull in. It'd not be good if we end up with non-reentrant versions of functions just because initially the backend isn't threaded etc. Greetings, Andres Freund
