First of all, sorry for taking too long to answer, Christmas kept me awfully busy :( Thanks a lot for catching the issue first, I didn't notice the spurious rebuilds when testing my patches. I have also reviewed and tested this one. I would split the two changes (the quoted string fix and the one to make the Makefile not depend on the extension) into two patches. Other than that feel free to add a Reviewed-by and Tested-by if you need :) Sincerely, Francisco Blas Izquierdo Riera (klondike)
