Hi,

  Is this yet another detail I do not understand, or is it some sort
of compiler bug?  Consider the following short program:

  // conv.cpp
  void  parsecomline  (int, const char**);

  int  main  (int argc, char **argv)
  {   parsecomline (argc, argv);
      return 0;
  }


This fails to compile with the following message:

  conv.cpp: In function `int main(int, char**)':
  conv.cpp:8: error: invalid conversion from `char**' to `const
char**'


This is the sort of conversion that I expect to work automatically. 
For example, the following program compiles just fine:

  //conv2.cpp
  void  f  (const char*);

  int  main  (void)
  {   char c, *cp = &c;
      f (cp);
      return 0;
  }
