    + PCode optimizations:
        1) Self := QSELF(), Self:method -> QSELF():method
        2) Declared, but unused variables are removed from code
      These optimizations are enabled if jump optimizations are enabled.

    + added recursive pcode tree tracer. It is capable to generate new
      warning: Variable %s is assigned, but not used. 
      Warning is not generated in these cases:
        1) unoptimal Self := QSELF() pcode [generated by preprocessor rules]
        2) if variable name starts with '_nowarn_'. This allows to 
           suppress warning in case unoptimal pcode is generated by 
           preprocessor rules
        3) assigned value is NIL. This let us force garbage collection
           using oVar := NIL
      Warning has warning level 3.
      ; NOTE: if you are using -w3 -es2 in makefiles, you'll need to fix your 
              redundant code to compile the project

    ; NOTE: I've been fixing warnings in utils/hbdoc/* for 2 hours, 
      but only fixed half of files. There are a lot of garbage code here.
      I do not thing this code is working... 
      I used fallback method: restored original files and used -w2
    ; NOTE: hbmake.prg has about 140 unused assignments.
      I've also fallback to -w2, because some of unused code is complex, 
      ex., ASCAN() with block parameters. I'm not using hbmake, and I'm 
      affraid to break something important. 

  * compiler/hbpcode.c
    - removed Ron's copyright on hb_compStrongType(). We do not have this 
      functions in the compiler at all. I guess this text is just a result 
      of .c header copy-paste from xHarbour's hbstrong.c some time ago.
