* source/rtl/isprint.c
     ! Fixed ISPRINTER() on Win32 after last changes.
       Thanks Guillermo, pls test now.
   
   * source/rdd/dbcmd.c
     ! Marked as HB_EXTENSION: FIELDLEN(), FIELDDEC(), FIELDTYPE()

   * include/hbextern.ch
   * source/rdd/dbcmd.c
     ! Marked as HB_EXTENSION: DBDROP(), DBEXISTS(), RDDINFO()
       (they were properly marked in hbextern.ch but not in source)

   * include/hbextern.ch
   * source/rtl/disksphb.c
   * source/rtl/fssize.c
   * source/rtl/fstemp.c
   * source/rtl/inkey.c
   * source/rtl/oemansi.c
   * source/rtl/philes.c
   * source/rtl/setcolor.c
   * source/rtl/setfunc.prg
   * source/rtl/setkey.c
   * source/rtl/shadow.c
   * source/rtl/trace.c
   * source/rtl/valtostr.c
   * source/vm/dynsym.c
     + Removed HB_EXTENSION from all the .prg level functions 
       prefixed with HB_.
       (there was a mixed situation here, but there's no need 
       to mark any HB_ functions as extensions, as it's obvious 
       by their name. So as a rule, no HB_ prefixed function 
       should ever be marked as HB_EXTENSION anymore.)
     ! Fixed some inconsistencies in HB_EXTENSION between 
       hbextern.ch and actual sources.

   * source/rtl/tgetlist.prg
     * One HB_EXTENSION changed to !HB_C52_STRICT because it 
       was guarding a bugfix rather than a real extension.

   * source/rtl/gui.prg
     * _GetNumCol() is now always strictly compatible.
       NOTE added about sloppy C5.3 behaviour.

   * source/rtl/inkey.c
   * contrib/xhb/xhb.ch
   * contrib/xhb/xhbfunc.c
     ! __KEYBOARD() xhb hidden parameter extension moved to 
       xhb lib. For similar functionality inside Harbour 
       pls use HB_KEYPUT(). __KEYBOARD is now 100% C5.x 
       compatible.

   * source/rtl/setfunc.prg
     * __SetFunction() extension now uses HB_KEYPUT() instead 
       of __KEYBOARD() extended parameters.

   * source/compiler/hbfunchk.c
   * source/rtl/at.c
     ! AT() extra parameters handled when HB_EXTENSION is on 
       (was !HB_C52_STRICT). (The first extra parameter is 
       XPP and Flagship compatible. The three parameter version 
       of this function is called AT3() in CAVO.)
     ! TRIM()/RTRIM() extra parameters handled on compiler level 
       when HB_EXTENSION is on (default).
     ! FILE() parameter check turned off in compiler.
       (to be C5.x compatible)

   * source/rtl/alert.prg
     ! ALERT() Harbour extended parameter (1st parameter type) 
       is now guarded with HB_EXTENSION instead of HB_C52_STRICT.

   * source/rtl/gete.c
     ! GETE[NV]() Harbour extended parameter guarded with HB_EXTENSION.

   * source/vm/proc.c
     ! PROCFILE() Harbour extended parameter guarded with HB_EXTENSION.

   * source/rtl/mlcfunc.c
     ! Harbour extended parameters for MEMOLINE()/MLCOUNT()/
       MLPOS()/MLCTOPOS()/MPOSTOLC() are now guarded with HB_EXTENSION 
       (instead of HB_C52_STRICT). It seems to be possible to 
       specify custom EOLs for all these functions. (Maybe simple 
       automatic Unix/Win EOL style handling would be better here)

   * source/vm/memvars.c
     ! Guarded Harbour extension in __MVRESTORE() with HB_EXTENSION.

   ; After this cleanup:
     - HB_EXTENSION is marking extra features living inside existing C5.x 
                    functions or classes, or Harbour extension functions 
                    not complying with the HB_ prefix rule (we have six 
                    such functions in RDD). If there are more extended 
                    parameters in Harbour pls mark them with HB_EXTENSION 
                    too.
     - HB_C52_STRICT is guarding bugfixes compared to C5.x.
     - No HB_ functions are guarded with HB_EXTENSION anymore.
     - We'd pbly need to review each HB_EXTENSIONs to check whether they 
       are safe or not.
     - A list of HB_EXTENSIONs:
       - MLCOUNT()
         MEMOLINE()
         MLPOS()
         MLCPOS()
         MPOSTOLC()      - 5th and up can specify custom EOLs.
       - ALERT()         - 1st parameter type can be any type in Harbour, char only in C5.x
       - SET FUNCTION TO
         __SETFUNCTION   - 2nd parameter can be numeric or array of numeric in Harbour.
       - SETKEY()        - 3rd codeblock parameter ("isactive" block)
       - SAVESCREEN()    - 5th parameter: lNoCheck (?)
         RESTSCREEN()    - 6th parameter: lNoCheck (?)
       - AT()            - 3rd and 4th parameters to set search range. 3rd parameter is 
                           also supported by XPP and FS. Results in compiler error in C5.x.
                           (CAVO uses AT2() and AT3() for extended versions.)
       - TRIM()
         RTRIM()         - 2nd parameter is an extension regarding space trimming mode.
                           Results in compiler error in C5.x.
       - ALLTRIM()       - 2nd parameter is an extension regarding space trimming mode.
       - GETE()
         GETENV()        - 2nd parameter specifies a default value. Can be found in HB_GETENV().
       - PROCFILE()      - 1st parameter is a Harbour extension. Undocumented function in C5.x.
                           The extension looks similar to the one found in Flagship.
       - __MVRESTORE()   - 3rd/4th parameters are Harbour extensions to set variable name 
                           mask. Redirected from the internal 5.x function named __MRESTORE().
       - DB*()           - cRDD, nConnection, cCodePage extra parameters in many DB*() functions.
                           TOFIX: None of them is marked as HB_EXTENSION.
       - SET()s          - These are not marked as HB_EXTENSION.
       - ?               - Is there anything else?
