    * Changed the way embedded zlib and pcre are handled:
      - They now reside in /external dir.
      - They are now excluded from Harbour dynlib. This means they
        will now be linked statically on non-*nix systems and
        dynamically on *nix systems. On *nix it's probably easy to
        switch to link statically. On non-*nix this is quite
        complicated to do.
      - If these libs are provided by the system, those will be used.
      - On non-*nix systems the locally hosted versions will be used,
        unless user overrides them using HB_INC_PCRE or HB_INC_ZLIB.
      - There is currently no officially supported way to force usage
        of locally hosted libs.
      - If PCRE lib is forcibly disabled or not found, build system
        will fall back to POSIX regex on *nix systems and Borland regex
        with bcc compiler. Otherwise it will stop the build with an error.
      - If zlib is forcibly disabled or not found, an error will be
        generated at build-time (in hbrtl). hbmzip is simply skipped
        in this case.
      - hbmk2 will use local builds of these libs if they are present
        in lib dir.
    ; TOFIX: hbmk script.
    ; TOFIX: dos builds. cmdline lenghts are most probably too big for them.
    ; NOTE: Bumps are expected.
    ; NOTE: I've yet to test/verify it.
