        * stacktrace.cc (GetStackTraceElements): Call
        gnu::gcj::runtime::NameFinder::removeUnknown() to determine if
        non-Java frames should be removed from a printed stack trace.
        Pass methodName to getLineNumberForFrame().
        (getLineNumberForFrame): Set method_name from info.dli_sname.
        * gnu/gcj/runtime/NameFinder.java (removeUnknown): New method.
        (remove_unknown): New variable.
        * include/java-stack.h (_Jv_StackTrace::getLineNumberForFrame):
        Add methodName arg.
