Check return values of functions declared with warn_unused_result
attribute in GLIBC 2.8. * cli/cli-cmds.c (pwd_command): Check return value from getcwd. * inflow.c (check_syscall): New function. (new_tty): Use check_syscall to check return values from open and dup. * linux-nat.c (linux_nat_info_proc_cmd): Check return value from fgets. * main.c (captured_main): Call cwd after setting up gdb_stderr; check for errors from getcwd. * mi/mi-cmd-env.c (mi_cmd_env_pwd): Check return value from getcwd. * ui-file.c (stdio_file_write): Ignore return value from fwrite. (stdio_file_fputs): Same. * utils.c (internal_vproblem): abort if last-ditch error message write fails.
