* thread_dbP.h (DB_FUNCTION): New macro. * structs.def: Use it for __nptl_create_event and __nptl_death_event. * db_info.c (DB_FUNCTION): New macro. * td_symbol_list.c (DB_FUNCTION): New macro, prepend "." to symbol name under [HAVE_ASM_GLOBAL_DOT_NAME]. (td_lookup) [HAVE_ASM_GLOBAL_DOT_NAME]: If lookup fails with PS_NOSYM and name starts with a dot, try it without the dot.
