/******** Fixing some special features of compilers **********
(c) 1997-2020 Jaroslav Fojtik
  if you don't use below mentionted compiler, please correct this items
  for your compiler and send me your correction to:
		fojtik@penguin.cz or JaFojtik@seznam.cz

Outputs: 
  __Strict_Const_Procs		compiler is very touht on const arguments
  __string_already_used		the class string is used internally
  __Disable_NULL_printf		the printf("%s",NULL) crashes
  __Ellipsis_Expand_Short       ellipse ... convert all char and short arguments to int
  __Limited_Proc_Size		several old compilers have severe limitation of procedure code size <24kB
  __No_bool			Compiler do not support bool type
  NO_LVAL_CAST			Compiler cannot compile ((char *)ptr)++
  __FixNonTemplateFriend	Templates are supported on the obsolette basis, needed <> after operator
  __Mkdir_Has_1_arg		Mkdir is defined with 1 argument only
  explicit			for compilers that do not support this keyword redefine it to "private:"
