Diagnose and guard against write errors dealing with config.status.
The general idea is this: all write failures from `configure'
writing `config.status' are indicated by $ac_write_error, which
is only checked at the end. This is safe because config.status
code is not executed before the file is complete. Other write
failures, be they inside config.status, or in sub shell/awk
scripts spawned from configure or config.status, typically need
earlier checking, as their results are used right afterwards.
* lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
before writing config.status, check afterwards.
(_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)

output to stdout.
