Hi.  Thanks for the report.  Could you investigate if the
tests/runtime-ipv6.c program return appropriately?  It is supposed to
check wether the runtime system supports IPv6 or not, and should detect
this properly on your system (or there is a bug in the self-test code
elsewhere).

Looking at the code, I don't think a getaddrinfo-lookup is sufficient,
the code probably need to attempt to listen to a socket too, in order to
fully test wether IPv6 is disabled globally or not.
