There's a very odd comment in this file: it clearly refers to some method in another file. But what was it for, anyway? Surely the name of a method and its signature is contained in the code. I'd just delete it.
/*
* Class: java_io_VMConsole
* Method: echo
* Signature: (Z)Z
*/
JNIEXPORT jstring JNICALL
Java_java_io_VMConsole_readPassword (JNIEnv * env,
jclass clazz
__attribute__ ((__unused__)),
jobject con)
