Looks like a false negative to me. Automake uses a deliberately-crippled compiler wrapper which is designed to reject command-lines with -c and -o for testing purposes, found in automake/t/ax/cc-no-c-o. The problem appears to be that the wrapper's test of the command line arguments is too simplistic, and incorrectly considers the above command line as a using both -c and -o, when it clearly does not. So the test will need to be made more robust. Cheers, -- Nick Bowler, Elliptic Technologies (http://www.elliptictech.com/)
