Description:
------------
configure makes certain attempts to find res_ndestroy() under various names, including for example __res_ndestroy() and innocuous_res_ndestroy, in various libraries including bind, resolv 

If I get it right, it finally finds this function in bind under __res_ndestroy name:

configure:79335: checking for __res_ndestroy in -lbind
configure:79360: cc -o conftest -I/usr/include -g -O2 -fvisibility=hidden  -L/usr/lib  -Wl,-rpath,/home/myaccount/php/install/lib -L/home/myaccount/php/install/lib conftest.c -lbind  -lresolv -lcrypt -lrt -lrt -lm -ldl -configure:79360: $? = 0
configure:79369: result: yes
c

and main/php_config.h gets the following entry:

#define HAVE_RES_NDESTROY 1

all of sudden, make fails


it looks like res_ndestroy used by configure as an alias to __res_ndestroy didn't make through and compiler still found res_ndestroy() calls, otherwise it would complaint about missed __res_ndestroy

if I comment out HAVE_RES_NDESTROY in php_configure.h and rebuild with make clean all, it fails on missed isfinite() function. Commenting out HAVE_ISFINITE brings yet another failure: undeclared CALLGRIND_STOP_INSTRUMENTATION and CALLGRIND_START_INSTRUMENTATION symbols. Finally commenting out HAVE_VALGRIND results in success.


Test script:
---------------
./configure --prefix=/home/myaccount/php/install \
 --disable-fileinfo \
 --with-libxml-dir=/home/myaccount/php/install && \
make



Actual result:
--------------
ext/standard/.libs/dns.o(.text+0x1608): In function `zif_dns_check_record':
php-7.2.0RC5/ext/standard/dns.c:422: undefined reference to `res_ndestroy'
ext/standard/.libs/dns.o(.text+0x1c1a): In function `zif_dns_get_record':
php-7.2.0RC5/ext/standard/dns.c:1013: undefined reference to `res_ndestroy'
ext/standard/.libs/dns.o(.text+0x1c9e):
php-7.2.0RC5/ext/standard/dns.c:937: undefined reference to `res_ndestroy'
ext/standard/.libs/dns.o(.text+0x1d60):

Is this still an issue for you with any of the actively supported
PHP versions[1]?  If so, which compiler and libc (please specify
the versions as well) are you using.
