        * gfortran.h (gfc_isym_id): Rename GFC_ISYM_NUMIMAGES to
        GFC_ISYM_NUM_IMAGES.
        (gfc_fcoarray): Add GFC_FCOARRAY_LIB.
        * intrinsic.c (add_functions): Update due to GFC_ISYM_NUM_IMAGES
        rename.
        * invoke.texi (-fcoarray=): Document "lib" argument.
        * iresolve.c (gfc_resolve_this_image): Fix THIS IMAGE().
        * libgfortran.h (libgfortran_stat_codes): Add comments.
        * options.c (gfc_handle_coarray_option): Add -fcoarray=lib.
        * simplify.c (gfc_simplify_num_images, gfc_simplify_this_image):
        Handle GFC_FCOARRAY_LIB.
        * trans.h (gfc_init_coarray_decl): New prototype.
        (gfor_fndecl_caf_init, gfor_fndecl_caf_finalize,
        gfor_fndecl_caf_critical, gfor_fndecl_caf_end_critical,
        gfor_fndecl_caf_sync_all, gfor_fndecl_caf_sync_images,
        gfor_fndecl_caf_error_stop, gfor_fndecl_caf_error_stop_str,
        gfort_gvar_caf_num_images, gfort_gvar_caf_this_image):
        New global variables.
        * trans-decl.c: Declare several CAF functions (cf. above).
        (gfc_build_builtin_function_decls): Initialize those.
        (gfc_init_coarray_decl): New function.
        (create_main_function): Call CAF init/finalize functions.
        * trans-intrinsic.c (trans_this_image, trans_num_images): New.
        (gfc_conv_intrinsic_function): Call those.
        * trans-stmt.c (gfc_trans_stop, gfc_trans_sync,
        * gfc_trans_critical):
        Add code for GFC_FCOARRAY_LIB.
