Rich Felker 19f8642494 report res_query failures, including nxdomain/nodata, via h_errno
while it's not clearly documented anywhere, this is the historical
behavior which some applications expect. applications which need to
see the response packet in these cases, for example to distinguish
between nonexistence in a secure vs insecure zone, must already use
res_mkquery with res_send in order to be portable, since most if not
all other implementations of res_query don't provide it.

    musl libc

musl, pronounced like the word "mussel", is an MIT-licensed
implementation of the standard C library targetting the Linux syscall
API, suitable for use in a wide range of deployment environments. musl
offers efficient static and dynamic linking support, lightweight code
and low runtime overhead, strong fail-safe guarantees under correct
usage, and correctness in the sense of standards conformance and
safety. musl is built on the principle that these goals are best
achieved through simple code that is easy to understand and maintain.

The 1.1 release series for musl features coverage for all interfaces
defined in ISO C99 and POSIX 2008 base, along with a number of
non-standardized interfaces for compatibility with Linux, BSD, and
glibc functionality.

For basic installation instructions, see the included INSTALL file.
Information on full musl-targeted compiler toolchains, system
bootstrapping, and Linux distributions built on musl can be found on
the project website:
