Configure with:
./configure --enable-code-coverage
Show coverage output with:
make code-coverage-capture
Built on m4/ax_code_coverage.m4 from the GNU autoconf archive
to provide the macros to check for presence of gcov + lcov;
upstream macro modified to:
- Remove use of $(AM_DEFAULT_VERBOSITY) , as earlier versions of
autoconf (such as the one used by default on Travis) do not have this.
- Rather than automatically defining CODE_COVERAGE_RULES to be a set
of makefile rules that use ifeq/endif (which is GNU make-specific),
instead only define CODE_COVERAGE_RULES if coverages is turned on,
and in that case don't use conditionals in the makefile.
On iPhone targets like iOS, watchOS or tvOS the file
/etc/resolv.conf cannot be used to configure cares.
Instead the resolver library is queried for configuration
values.

Some basic checks we make were placed early enough in generated
configure script when using autoconf 2.5X versions. Newer autoconf
versions expand these checks much further into the configure script,
rendering them useless. Using XC_CONFIGURE_PREAMBLE fixes placement
of early intended checks across all our autoconf supported versions.
Tested with:
buildconf: autoconf version 2.69
buildconf: autom4te version 2.69
buildconf: autoheader version 2.69
buildconf: automake version 1.13.1
buildconf: aclocal version 1.13.1
buildconf: libtool version 2.4
buildconf: GNU m4 version 1.4.16
CARES_BUILDING_LIBRARY and CARES_STATICLIB no longer defined in ares_config.h,
configure will generate appropriate conditionals so that mentioned symbols
get defined and used in Makefile derived from Makefile.am at compilation time.
Recent versions of libtool are now tracing usage of AC_CONFIG_MACRO_DIR
macro and warn heavily when not used in configure script along with
ACLOCAL_AMFLAGS in Makefile.am. So in order to make libtool happy
while keeping backwards compatibility this is added.
Define HAVE_INET_NET_PTON only when system's inet_net_pton function is IPv6
capable and is not affected by the WLB-2008080064 advisory.
HAVE_INET_NET_PTON_IPV6 is no longer defined nor used.

The purpose of the whole patch was to silence a compiler warning triggered
with GCC 4 on file ares_process.c The specific compiler warning was
'dereferencing type-punned pointer might break strict-aliasing rules'.
A simpler patch will follow to equally silence the warning.
AIX, at least, does not have sockaddr_storage.ss_family member.
Detect this in the configure logic and use proper #ifdefs in the
ares_process logic.

This helps find compile warnings because they simply break
the build.
