      * fixed compilation of code that uses '@' pass by
       reference. The following syntax is no longer supported:
       var := IIF( .T., @var, var )
       however you can still use the following:
       funcall( IIF( bPassbyRef, @someVar, someVar ) )
      +added support for the following statement:
         WITH OBJECT <objexpression>
            ...
         END
       inside this statement you can use simplified form of sending
       messages to the object specified by <objexpression>
         :message( )    instead objexpression:message()
         :property      instead objexpression:property
       The runtime error will be generated at the time of message
       sending (or property access/assign) if <objexpression>
       is not a value of type object.
       You can use the reserved property:
         :__withobject
       to access/assign the controlling object.
      *fixed support for command line response file (@file.clp)
       to be compatible with Clipper (Clipper genertes a single
       obj file)
      *fixed memory leaks when there is a fatal error in autoopened
       module (using DO ... statement)
      *implicit startup functions are removed from the list of
       functions before generation of output code

   * source/pp/ppcomp.c
   * source/pp/pplib.c
   * source/pp/ppcore.c
      * redefinition of #define no longer causes a memory leak
      * fixed repeatable optional clauses
         #xcommand SET <var1> [, <varN>] WITH <val> =>
          <var1>:=<val>[; <varN>:=<val>]
      * fixed compilation of optional clauses (when used in different
        order then declared) -this fixes the following long
        waiting bug:
         #command MYCOMMAND [<mylist,...>] [MYCLAUSE <myval>] => ;
            MyFunction( {<mylist>} [, <myval>] )
         MYCOMMAND MYCLAUSE 321 "HELLO"
      * fixed restricted macro match marker <x:&>

   * tests/Makefile
   - tests/pretest.prg
   + utils/hbpptest
   + utils/hbpptest/Makefile
   + utils/hbpptest/pretest.prg
      * moved file 'pretest.prg' from tests to separate directory
        to make easier validation of the preprocessor

   * TODO
      * added note to fix hb_objGetMethod() so it will not generate
        error if there is no method

   * doc/en/clipper.txt
      * added documentation for WITH OBJECT usage
