GCJ fails with 

   Can't find default package 'core'. ... 

when a class source file specifies `import core.*'.   A full example is 
outlined below. 

If you try to compile this `project' like 

  gcj -d . src/Main.java src/core/Foo.java 

the above mentioned error is reported.  The same project works fine
with Sun's or Blackdown's Java compiler. 

Suppose we have the directory structure 

  > find . 

with the following contents of `src/Main.java': 

  // commenting out this line makes the classes compile. 
  import core.*;

  public class Main 
      public Main() 
          core.Foo foo = new core.Foo();
      public static void main(String args[]) 
          Main m = new Main();

and the following contents of `src/core/Foo.java': 

  package core;

  public class Foo 
      public Foo()
      public void print() 
        System.out.println("Hello, world");

Note that -d doesn't do anything when compiling to object.
However, adding -C doesn't help either.

A simple workaround is to add -Isrc.

This is fixed on the gcj-eclipse branch, I marked this PR as
depending on PR 28067.

Perhaps gcj needs to handle -combine properly.
That would also help fix this, I think.

All gcj front end bugs have been fixed by the gcj-eclipse branch merge.
I'm mass-closing the affected PRs.
If you believe one of these was closed in error, please reopen it
with a note explaining why.
