* Makefile.in: Rebuilt.
* Makefile.am (java/lang/ClassLoader.h): Make _Jv_RunMain a
friend.
* prims.cc: Include ClassLoader.h.
(_Jv_RunMain): When executing jar files, classpath must be the jar
file only. Lose our reference to the system ClassLoader in order
to get a new one with the correct classpath.
* java/lang/natSystem.cc (init_properties): When executing a jar
file, only use the jar file for java.class.path.
* gnu/gcj/runtime/VMClassLoader.java: Use the canonical file name
for bytecode archives.
* gnu/gcj/runtime/FirstThread.java: Handle case where manifest
exists, but not Main-Class.
