stacktrace.cc (_Jv_StackTrace::UnwindTraceFn): Protect interpreter-specific code with #ifdef INTERPRETER.

2005-03-15  Andreas Tobler  <a.tobler@schweiz.ch>

        * stacktrace.cc (_Jv_StackTrace::UnwindTraceFn): Protect
        interpreter-specific code with #ifdef INTERPRETER.
        (_Jv_StackTrace::getLineNumberForFrame): Likewise.
        (_Jv_StackTrace::FillInFrameInfo): Likewise.
        (_Jv_StackTrace::non_system_trace_fn): Likewise.
        * include/java-stack.h (struct _Jv_InterpFrameInfo): Protect  with
        #ifdef INTERPRETER. Also protect declarations that use it.
        * java/lang/Class.h: Move _Jv_StackTrace friend declaration  outside
        #ifdef INTERPRETER block.
