>Description:
 GCJ-3.0 fails to compile simple java programs whose main class
 file has a package declaration

>How-To-Repeat:

Here's a file Test.java:

,----[ Test.java ]
| package gnu.foo;
| 
| class Test {
|     public static void main(String[] args) {
| 	System.out.println("Hello, World!");
|     }
| }
`----

Compiling it fails like:

,----[ *compilation** ]
| gcj-3.0 -o Test --main=Test Test.java
| /tmp/cctAs4jG.o: In function `main':
| /tmp/ccvuhFZz.i(.text+0x2e): undefined reference to `Test::class$'
| /tmp/ccvuhFZz.i(.text+0x32): undefined reference to `Test::class$'
| collect2: ld returned 1 exit status
`----

>Fix:
 If I remove the package declaration, everything seems to work
 fine.  I've experienced this with larger packages; I believe it's
 just having a package declaration in the file with the "main" function
 that causes a failure.
