[patch] fix c++ compilation warnings and test cases

[Andreas Tobler <toa at pop dot agri dot ch>]

Hi all,

this patch introduced|uncovered a c++ issue in java/lang/Class.h

http://gcc.gnu.org/viewcvs?view=rev&revision=126219

Right now all *.cc testcases fail due to the ? redundant ?
declarations in Class.h. Also the compilation of the *.cc source files 
spits this warning:

java/lang/Class.h:276: warning: declaration 'struct 
java::lang::ClassLoader' does not declare anything

etc ....

I tested the attached patch on i686-darwin and ppc-darwin.

Maybe a c++ experienced person has an additional comment.

I think it is ok, but I'm not c++ experienced, I only look at the 
compilation and the test case run ;)

Tom, does the // Friend classes comment only belong to the declarations 
I'd like to remove or also to the following ones?

Ok for main?

Thanks,
Andreas
