libmysql: fix musl compatibility #385
Conversation
The musl C library does not support res_ninit, res_nsearch and res_nclose. Check if res_ninit is defined, and use res_search if not. Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>

musl doesn't have res_n* functions so we are falling back to the not thread safe ones. Note that another approach was submitted at https://bugs.mysql.com/bug.php?id=106034 (mysql#385) but that is arguably less portable given it takes the new path for everything non-glibc where things may already work fine (e.g. Solaris). This patch is less invasive. Bug: https://bugs.gentoo.org/761352 See also: mysql#385 See also: https://bugs.mysql.com/bug.php?id=106034
