Given that a false-negative would just fallback to build (I hope???
That's surely the only sane option) then this issue must have been due
to false positives...

Can anyone contruct a file of some kind that will give a false-positive
for the various proposed detection routines?

Bonus points if it's a Makefile, since that would be a more powerful
argument for it being impossible...
