But I'm almost certain you didn't copy and paste from your configure.ac, so maybe in the rewrite for this email, you changed the quoting? > > If I have an instance of AC_LANG_PROGRAM usage earlier in the file that > has been working fine.

Can you post a complete configure.ac file that reproduces the problem (preferably trimming to a minimal testcase first), so we can see if something earlier in the file may be impacting how this line is expanded? - -- Don't work too hard, make some time for fun as well!
