Hi, Maarten!
Sorry for the delay! I'm not sure that these macros should be AC_DEFUN_ONCE,
because potentially they could be called several times with different values
of $PERL/$RUBY to find values for different kinds of interpreter. But I don't
have a strong position on this point. Do you think that I better maker them
one-shot?
As for the caching -- do you have any pointers on how to implement a proper
caching? I can certainly use AC_CACHE_VAL, but then if the value of $RUBY
changes between runs it will pick up wrong values? Or will the cache be
discarded automatically in this case?
Thanks!
