+ # Xcode 15 offers only a macOS Sonoma SDK, which

+ # This means that AC_CHECK_FUNCS() will think
+ # that the remote-capture APIs are present,
+ # including pcap_open() and
+ # pcap_findalldevs_ex().
+ #
+ # However, they are *not* present in macOS
+ # Ventura and earlier, which means that building

+ # that fail to start because one of those APIs
+ # isn't found in the system libpcap.
+ #
+ # Protecting calls to those APIs with

+ # doesn't even allow the program to compile with
+ # versions of Xcode prior to Xcode 15, as the
+ # pcap.h file doesn't specify minimum OS
+ # versions for those functions.
+ #
+ # Given all that, and given that the versions of

+ # point in checking for pcap_open() if we're

+ #
+ # However, if we're *not* linking against the
