Could you please check this into 3.0.1, too?

Hi Jeff,
thanks for committing the two patches.

Here are my two favorites:
2001年05月03日 Tom Tromey <tromey@redhat.com>
	* java/lang/natRuntime.cc (init): Call add_library on the program
	itself.
	(_Jv_FindSymbolInExecutable): Return NULL if no library on the
	list has the symbol.

 lt_dlinit ();

 }
 
and this important one (it causes an infinite loop for my application):

I would be glad, if these patches could be applied, too.
Thanks, Martin.
PS: I cc'ed the java list, so other people can make suggestions, too.
