[Kaffe] ease of use patch.

[Moses DeJong]

Hello.

Here is a quick patch to fix a really common error
that I make all the time. It would be nice if Kaffe
gave a helpful error for this case. This is really an
"ease of use" issue and not a bug but I think people
might like this feature.


(before patch)

% kaffe ReflectedFloatBug1.java
java.lang.NoClassDefFoundError: ReflectedFloatBug1/java
        at java.lang.Throwable.<init>(Throwable.java:37)
        at java.lang.Error.<init>(Error.java:21)
        at java.lang.LinkageError.<init>(LinkageError.java:21)
        at java.lang.NoClassDefFoundError.<init>(NoClassDefFoundError.java:21)


(after patch)

% kaffe ReflectedFloatBug1.java
You probably meant ReflectedFloatBug1

	* kaffe/kaffe/main.c: helpful error message added for the
        case where kaffe is invoked with XXX.java as the class name.
