dnl needs.  Using `AC_CANONICAL_TARGET' is enough to run the two other

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