Hi Noah, Thank you for the quoting hint. Now, I have a follow-up question: How is anybody supposed to know whether/when double quoting is necessary? It is because of the quoting ambiguity (ambiguity to the way I think, anyway;) that I created these two web pages: http://Autogen.SourceForge.Net/acquoting.html http://Autogen.SourceForge.Net/conftest.html In fact, you can recreate the the function in my email by filling in the form on the second page with straight-up information and a CGI engine deals with quoting and protecting square brackets. :-) I just missed the part about where I needed *two* layers of quotes for the second cache value arg. So, if I can figure out how to determine when two are needed and when one is enough, I can add that to those pages. :) Thanks again - Bruce _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
