    ! fixed name conflict in privates/publics declaration.
      Harbour allows to declare memvars with the same name as file
      wide statics or fields but this extensions was not working well
      in some cases and can cause unexpected results in variable
      declaration, f.e. try this code:
               static v:="static"
               proc main()
                  public v:="public"
                  ? v, M->v
               return
      compiled with -n -w switches and also with -n -w -a before
      this fix.
    ! fixed some compile time warnings in memvars declaration to be
      more Clipper compatible
    ! fixed compiling external modules (DO <procname> [WITH <params,...>])
      when function <procname> is already declared but with different
      letter case. Harbour does not convert <procname> in DO statement
      to upper case to play well with case sensitive file systems and
      it could cause confusing warning message:
         Cannot open <procname>.prg, assumed external

  * harbour/source/compiler/harbour.yyc
    ! added protection against bug in bison destructors which might cause
      multiple free the same memory block on syntax error due to 

  * harbour/source/rdd/dbf1.c
    ! added missing binary flag for daytime fields

  * harbour/source/rdd/dbfntx/dbfntx1.c
    ! fixed possible memory leak during accessing corrupted NTX files
    ! fixed possible GPF during accessing corrupted NTX files

  * harbour/source/compiler/genc.c
    * minor cleanup

  * harbour/config/os2/global.cf
    ! use FOR command to delete group of files
