+ # the run-time linker, without the executable having to be
+ # linked with those libraries. (This allows a library to be
+ # changed to depend on more libraries without breaking that
+ # library's ABI.)
+ #
+ # The only way to test for that support is to see if the
+ # script contains the string "static-pcap-only"; we can't
+ # try using that flag and checking for errors, as the
+ # versions of the script that didn't have that flag wouldn't
+ # report or return an error for an unsupported command-line
+ # flag. Those older versions provided, with --static, only
+ # the libraries on which libpcap depends, not the
+ # dependencies of those libraries; the versions with
+ # --static-pcap-only provide all the dependencies with
+ # --static, for the benefit of programs that are completely
