From configure.ac:

    if test "${HAVE_W32}" = "yes"; then
      EMACS_CHECK_MODULES([HARFBUZZ], [harfbuzz >= 1.2.3])
    else
      EMACS_CHECK_MODULES([HARFBUZZ], [harfbuzz >= 0.9.42])
    fi

and the configure output says:
    checking for harfbuzz >= 0.9.42... yes

I guess we could put the version in the warning as well, but it seems
a little excessive.
