  * src/rtl/hbgtcore.c
    * made hb_gtCreate() and hb_gtReload() calls compatible with
      "vszHarbour" by Viktor Szakats after https://github.com/vszakats/harbour-core/commit/42a0cc24476e38ee8f54019cb8f6e2e7edab808a

      hb_gtCreate() without parameter doesn't do anything in this version,
      "NUL" and additionally "GTNUL" are supported. The same applies to
      hb_gtReload().

    - deleted one more occurrence of hb_stricmp( szGtName, "null" ) in
      hb_gtLoad(). If i'm not mistaken, such variaton isn't used anywhere
      in Harbour codebase.
