I've committed these two patches, with the suggestion made by Joel.

2009-01-06  Jim Blandy  <jimb@red-bean.com>

	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.

	* top.c (gdb_init): Don't set the current directory here; that's
	already been done in captured_main.
