# intl sister-directory configuration rules.

# The idea behind this macro is that there's no need to repeat all the

# autoconf probes done by the intl directory - it's already done them

# for us.  In fact, there's no need even to look at the cache for the

# answers.  All we need to do is nab a few pieces of information.

# The intl directory is set up to make this easy, by generating a

# small file which can be sourced as a shell script; then we produce

# the necessary substitutions and definitions for this directory.
