   9 dnl `AC_CANONICAL_HOST', or `AC_CANONICAL_TARGET', depending on the
  10 dnl needs.  Using `AC_CANONICAL_TARGET' is enough to run the two other
  11 dnl macros.
  12 dnl
  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.
  20 dnl
