        * main.c (captured_main): Remove 'count' varible and the
        ALIGN_STACK_ON_ENTRY block that used it.  Error out if --core and
        --pid options were issued simultaneously.  If an explicit pid
        option was passed, don't fallback to core file.  Detect extra
        arguments better in the presence of explicit pid or core
        arguments.

2008-01-05  Joel Brobecker  <brobecker@adacore.com>

        * ada-lang.c (ada_which_variant_applies): Correctly compute

2008-01-03  Joel Brobecker  <brobecker@adacore.com>

        * ada-lang.c (ada_array_bound_from_type): Make non-static.
        Handle properly the case when the index type is an enumerated type.
        Do not return the subtype of the bounds type, just return the
        bounds type directly - this is not needed and is more consistent
        with what we do for arrays when no XA parallel type exists.

2008-01-03  Joel Brobecker  <brobecker@adacore.com>

        * ada-lang.c (static_unwrap_type): Add forward declaration.
        (template_to_static_fixed_type): Fields of dynamic types sometimes

        for the tag.
        (ada_to_fixed_type): Add check_tag parameter; do not look for
        tag if null.  When looking for a tag, use a fixed record type.
        * ada-lang.h (ada_to_fixed_type): Add check_tag parameter.
        * ada-valprint.c (printable_val_type, ada_value_print): Update

2008-01-02  Joel Brobecker  <brobecker@adacore.com>

        * ada-lang.c (ada_evaluate_subexp): Modify the value returned
        when noside is EVAL_AVOID_SIDE_EFFECTS to be an lval_memory.
        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.

2008-01-02  Joel Brobecker  <brobecker@adacore.com>

        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
