   4 # The idea behind this macro is that there's no need to repeat all the
   5 # autoconf probes done by the intl directory - it's already done them
   6 # for us.  In fact, there's no need even to look at the cache for the
   7 # answers.  All we need to do is nab a few pieces of information.
   8 # The intl directory is set up to make this easy, by generating a
   9 # small file which can be sourced as a shell script; then we produce
  10 # the necessary substitutions and definitions for this directory.
