    * restored support for old hb_inLine() syntax
    + added support for hb_inLine() to new PP. It can be enabled by
      -kI compiler switch. It's disabled by default.
      The new hb_inLine{} syntax is:
         [ <exp> ] hb_inLine [ ( [<params,...>] ) ] { [ <c_code> ] } [ <exp> ]
      <c_code> can contain new line characters.
      Nested hb_inLine{} in <params,...> is not supported. If you think
      it's important I can add it in few lines.
      This version does not break any valid Clipper syntax, hb_inLine is
      not reserved word and hb_inLine can be repeated many times in the
      same line. F.e. this code can be properly preprocessed and compied if
      you disable in compiler old hb_inLine() syntax and enable the new one
      by -kcI Harbour compiler switch:

         proc main()
         local hb_inLine := " (var) "
         ? hb_inLine{ hb_retc("inLine"); } + hb_inLine(" parameter ") {
              hb_retc( hb_parc( 1 ) );
              } + "!" + hb_inLine + hb_inLine() { hb_retc( ":-)" ); } + ;
           hb_inLine() + "{}"
         return
         function hb_inLine()
         return " func() "

      So from user point of view this version have real "inline" syntax.
      To be clear: I'm not a fun of any C inline extensions. They works
      only when we use .c code as compiler backend so the code which uses
      them cannot be used in .hrb files and any other format we will add
      in the future which do not support later C code compilation. F.e it
      will not work in compiler integrated with HVM or with .NET
      Anyhow if someone finds it useful then I think that it should be
      properly implemented. This is the reason I added the new version.
      The old one I left only for backward compatibility. It breaks any
      code which uses hb_inLine keyword can be used only once in a line
      and it does not have "inline" so IMHO it should not be enabled by
      default.
      I would like to hear your opinion about default compiler switches:
         1. should we disable both: hb_inLine() and hb_inLine {}
         2. should we disable hb_inLine() and enable hb_inLine {}
         3. should we disable hb_inLine {} and enable hb_inLine()
         4. should we enable both: hb_inLine() and hb_inLine {}

  + harbour/tests/hbinline.prg
    + added test code for new hb_inLine{} syntax

  * harbour/tests/inline_c.prg
    ! replaced direct access to HB_ITEM body by API function calls
