Forgot to mention I used
AUTOCONF_VERSION=2.69
PHP_AUTOCONF=/usr/local/bin/autoconf-2.69

as build.mk wouldn't pick up my autoconf on this box. That one could totally be my fault
though.

Expected result:
----------------
Build should work.

Replacing 

#if HAVE_NET_IF_H
# include <net/if.h>
#endif

with

# include <net/if.h>

in https://github.com/php/php-src/blob/master/ext/standard/net.c#L26

fixes this. Maybe it's an autoconf oddity? autoconf version is 2.69
ac_cv_header_net_if_h=no in config.log
