>Description:
awk doesn't set error exit status on errors:

% awk '{if ($1 == '1') print 2}' <&- && echo OK || echo FAILED
awk: i/o error occurred on /dev/stdin
 source line number 1
awk: i/o error occurred while closing /dev/stdin
 source line number 1
OK

GNU awk, however, behaves correctly:

% gawk '{if ($1 == '1') print 2}' <&- && echo OK || echo FAILED 
gawk: cmd. line:1: fatal: error reading input file `-': Bad file descriptor
FAILED

>How-To-Repeat:
See description.
