[PD] Cross platform path for externals ?

[David Medine via Pd-list]

Hey, Jaime!
It also occurs to me that there must be some easy C way to return the 
current path. cd does it, why can't you? A crude solution might be to 
put some platform specific #ifdef statements into the code, but that may 
not get to the heart of your problem.
