Good work.

There's more than one way to solve most of these (annoying) problems/differences, and we might want to tweak the style as we figure out more appropriate solutions.  But for now, this establishes a good baseline.

test/nativepath/NativesOK.java line 36:

> 36:         String c_native = System.getProperty("correct.nativepath").replace("/", File.separator);

the name "correct.nativepath" is slightly off, since it needs to be fixed up, but well, ... it works!
