This file has two functions JSS_getPtrFromProxy, JSS_ptrToByteArray that duplicate functions in jssutil.c. File NativeProxy.c is not compiled during 
normal build process. Looks like a dead code.

NativeProxy.c and NativeProxy.java seems to have quite a few references in JSS code, EG: CipherContextProxy.java, KeyProxy.java, ModuleProxy.java etc . If this is dead code, then quite a few classes will have to be modified.

Listing of reference to NativeProxy:

./org/mozilla/jss/pkcs11/CipherContextProxy.java

final class CipherContextProxy extends NativeProxy {
./org/mozilla/jss/pkcs11/KeyProxy.java
