        This is needed to make sure that any other treatment applied
        to the resulting value does not fail for spurious reason,
        such as trying to take the address of this value.

        * ada-lang.c (ada_value_equal): Dereference reference types when
        comparing arrays.

        Updated copyright notices for most files.

2008-01-01  Christopher Faylor  <me+gdb@cgf.cx>

        * win32-nat.c (psapi_module_handle): Remove static.
        (get_module_name): Rename from psapi_get_dll_name.  Revamp slightly to
        return first module found if base_address is zero.  Don't initialize
        psapi function pointers here.  Convert to cygwin paths when
        appropriate.
        (win32_pid_to_exec_file): Use Cygwin's /proc interface to determine
        executable name.  Use get_module_name when that fails or when
        !__CYGWIN__.
        (_initialize_psapi): New function.  Initialize psapi stuff before it is
        needed or issue a warning if it is not found.  Move psapi_module_handle
        here.

2008-01-01  Joel Brobecker  <brobecker@adacore.com>

        * ada-lang.c (ada_remove_trailing_digits): New function.
        (ada_remove_po_subprogram_suffix): New function.
        (ada_decode): Improve. Move the description of the algorithm
        directly inside the code, instead of in the function global
        description.

2008-01-01  Joel Brobecker  <brobecker@adacore.com>

        * ada-valprint.c (ada_val_print_1) [TYPE_CODE_REF]: Ignore deref_ref
        and always print the dereferenced value.

2008-01-01  Joel Brobecker  <brobecker@adacore.com>

        * ada-lang.c (ada_evaluate_subexp, case BINOP_SUB): Add handling
        of the case where the first argument is a reference.
        (ada_evaluate_subexp, case BINOP_ADD): Likewise.

2008-01-01  Joel Brobecker  <brobecker@adacore.com>

        Implement support for Ada interface types.

        * ada-lang.c (ada_is_dispatch_table_ptr_type): New function.
        (ada_is_ignored_field): Ignore fields that are a dispatch table
        of a tagged type.

2008-01-01  Joel Brobecker  <brobecker@adacore.com>

        * top.c (print_gdb_version): Update copyright year.
