* harbour/include/hbcomp.h
    + added extern hb_comp_szFile

  * harbour/include/hbinit.h
    * changed hb_vmProcessSymbolsExt() to hb_vmProcessSymbolsEx() respecting
      Mindaugas suggestion.
    + added HB_INIT_SYMBOLS_EX_END() macro
    * translate HB_INIT_SYMBOLS_END() macro to HB_INIT_SYMBOLS_EX_END()

  * harbour/include/hbsetup.h
    + added HB_PCODE_VER_MIN and HB_PCODE_VER both now are set to 0x0001

  * harbour/include/hbtypes.h
    * changed VM_PROCESS_SYMBOLS_EXT to VM_PROCESS_SYMBOLS_EX

  * harbour/include/hbvm.h
    + added hb_vmFindModuleSymbolName() - it returns the file name of given
      symbol if it was registered in HVM

  * harbour/source/compiler/genc.c
    * set HB_FS_LOCAL for local module functions
    * use HB_INIT_SYMBOLS_EX_END instead of HB_INIT_SYMBOLS_END

  * harbour/source/compiler/harbour.c
    * minor modifications

  * harbour/contrib/rdd_ads/ads1.c
  * harbour/source/rdd/dbf1.c
  * harbour/source/rdd/delim1.c
  * harbour/source/rdd/sdf1.c
  * harbour/source/rdd/dbfdbt/dbfdbt1.c
  * harbour/source/rdd/dbffpt/dbffpt1.c
  * harbour/source/rdd/dbfcdx/dbfcdx1.c
    * added HB_FS_LOCAL to function symbols in registered symbol tables

  * harbour/source/rdd/dbfntx/dbfntx1.c
    * added HB_FS_LOCAL to function symbols in registered symbol tables
    ! added missing break
    + added DBOI_KEYCOUNTRAW, DBOI_KEYNORAW. They works like DBOI_KEYCOUNT
      and DBOI_KEYNO in pure DBFNTX. Only with some upper level RDDs like
      RMDBFNTX which supports bit map filters they can return differ results.

  * harbour/source/rdd/workarea.c
    * changed ORDERINFO to DBORDERINFO in error message

  * harbour/source/rtl/set.c
    * respect previous settings in logical SETs if given value is not valid
      new one.
    + added misinf initialization for _SET_FORCEOPT and _SET_HARDCOMMIT.
    * changed default value of _SET_OPTIMIZE to TRUE

  * harbour/source/vm/dynsym.c
    * give the highest priority for LOCAL function symbols

  * harbour/source/vm/hvm.c
    + added hb_vmFindModuleSymbolName() - it returns the file name of given
      symbol if it was registered in HVM
    * changed hb_vmProcessSymbolsExt() to hb_vmProcessSymbolsEx() and added
      PCOE version checking

  * harbour/source/vm/maindllp.c
    * changed hb_vmProcessSymbolsExt() to hb_vmProcessSymbolsEx()
    * changed VM_PROCESS_SYMBOLS_EXT to VM_PROCESS_SYMBOLS_EX

  * harbour/source/vm/proc.c
    * changed to use stack macros/functions instead of direct accessing
      HB_STACK members
    + implemented PROCFILE() - it returns now real source file name
      with body of given function symbol or function executed at given
      stack level. If the source file cannot be detected then empty
      string is returned. Unlike in xHarbour it works also for static
      functions. synatx:
         PROCFILE( [ <FuncSym> | <nStackLevel> ] )
      F.e.:
         PROCFILE() -> current module name
         PROCFILE(@DBFCDX())  -> ../../dbfcdx1.c
