+ * guile/scm-breakpoint.c (gdbscm_breakpoint_commands): Use
+ ui_file_as_string and adjust to use std::string.
+ * guile/scm-disasm.c (gdbscm_arch_disassemble): Likewise.
+ * guile/scm-frame.c (frscm_print_frame_smob): Likewise.
+ * guile/scm-type.c (tyscm_type_name): Use ui_file_as_string and
+ adjust to use std::string. Throw exception directly instead of
+ returning it in EXCP output parameter.
+ (tyscm_print_type_smob, gdbscm_type_print_name): Adjust to
+ tyscm_type_name interface change.
+ * guile/scm-value.c (vlscm_print_value_smob, gdbscm_value_print):
+ Use ui_file_as_string and std::string.
