Well, there is a good reason for paths in GNU make to be unix-paths. You define
a rule as:


for target C depending on B. If you use windows native paths something like:


is valid and can mean either target C depending on target B:D or target C:B
depending on target D. IIRC there are some heuristics in the DOS/Windows native
version GNU make, but I am not even sure if cypath has those too (and as this
is a cornercase: if they are reliable). Also, it is not only make itself that
has to take care of this, but also the little Perlhelpers etc that fiddle with
this. IMHO, keeping the paths unixy is the safest bet.
