I am no expert at this, but for example a "/" is not allowed in windows 
filenames (so it should not be in windows path at all. Of course a user 
can still put it in there...)
On unix, it is likely to be there => unless the path is almost empty

Can the makefile check the existence of a directory? (and would this 
check obey the \/ difference?)
If so (the root directory)  /  should always exist on unix.
But on windows "/" is not allowed in filenames, and can not exist.

Only I do not know, what happens with mounted filesystems....

or test if ./known.file exists...
