Subject: Incompatible behaviour of res_query(3) w.r.t. NXDOMAIN

  Hello,


Musl’s res_query(3) returns success for a query that results in an NXDOMAIN response, which disagrees with other common implementations.

Simple test case: https://t.rb67.eu/res_query.c

On Debian Linux, OpenBSD and FreeBSD this program prints:

  error: Unknown host

but on Alpine Linux edge (musl v1.2.1):

  success (size 91)



Best regards,
Daniel
