* class.c (add_proc_comp): Add static initializer for PPCs.
(add_procs_to_declared_vtab): Modified comment.
* module.c (mio_component): Add argument 'vtype'. Don't read/write the
initializer if the component is part of a vtype.
(mio_component_list): Add argument 'vtype', pass it on to
'mio_component'.
(mio_symbol): Modified call to 'mio_component_list'.
* trans.h (gfc_conv_initializer): Modified prototype.
(gfc_trans_assign_vtab_procs): Removed.
* trans-common.c (create_common): Modified call to
