Compiling GCC With a C++ Compiler (g++)

[Ranjit Mathew <rmathew at gmail dot com>]

Hi,

  If I try compiling bits that include "gcc/tree.h" with
g++, I get:

/home/ranmath/src/gcc/gcc/gcc/tree.h:2504: error: member 'tree_string tree_node::string' with copy assignment operator not allowed in union

The definition of tree_string is:

  struct tree_string GTY(())
  {
    struct tree_common common;
    int length;
    const char str[1];
  };

If the "const" is removed from above, the compilation
proceeds.

There were a flurry of patches to make GCC compilable
with a C++ compiler in the recent past and I thought
it was now done... Didn't anyone else run into this?
(Apart from Tom, who suggested the fix above.)

Is this a bug? If yes, is it in the C++ compiler or
in the definition of tree_string?

Thanks,
Ranjit.
