Do you actually understand why make is displaying those warning
messages in the first place? From what I understood from the make
manual, it typically happens when you call "make" directly for a
subdirectory instead of using $(MAKE). A quick test on a simple example
seems to confirm that.

However, I see that canfestival seems to be using $(MAKE) everywhere,
so I don't see why make decides that the jobserver is not available.

Thanks,

Thomas
