9 dnl `AC_CANONICAL_HOST', or `AC_CANONICAL_TARGET', depending on the

13 dnl As nothing in the Wireshark is itself a build tool (we are not,
14 dnl for example, a compiler that generates machine code), we probably
15 dnl don't need AC_CANONICAL_TARGET, so, in theory, we should be able
16 dnl to use AC_CANONICAL_BUILD and AC_CANONICAL_HOST - or perhaps just
17 dnl AC_CANONICAL_HOST - instead.  Note that we do have tools, such as
18 dnl lemon, that need to be built for the build machine, not for the
19 dnl host machine, so we might need both.
