Hi,
this is version of patch which bootstrap®ress all languages at x86_64. OK?
Honza
* trans-types.c (gfc_array_range_type): Remove.
(gfc_init_types): Do not build gfc_array_range_type.
(gfc_get_array_type_bounds): Do not put unrealistic array bounds.
* trans-types.h (gfc_array_range_type): Remove.
* tree-pretty-print.c (dump_array_domain): Dump empty domain as
[0:].
