cat < /dev/null fail.

[Kazuhiro Fujieda]

Since the 199-Jul-17 snapshot, commands with redirection of the
standard input, such as `cat < /dev/null' have failed in the
notty mode on Win9x.

$ cat < /dev/null
    0       0 [main] C:\CYGNUS\CYGWIN~1\H-I586~1\BIN\cat.exe 1002 spawn_guts: wait failed: nwait 3, pid 1002, winpid -231673, Win32 error 6
    0    4921 [main] cat 1002 spawn_guts: waitbuf[0] 0x1F 0
20653   25574 [main] cat 1002 spawn_guts: waitbuf[1] 0x12 = 0
$

I can't collect a strace log, because the strace command fails
as the following.

$ strace -o /tmp/strace.log cat < /dev/nul
    0       0 [main] C:\CYGNUS\CYGWIN~1\H-I586~1\BIN\strace.exe 1005 spawn_guts: wait failed: nwait 3, pid 1005, winpid -232277, Win32 error 6
    0    5059 [main] strace 1005 spawn_guts: waitbuf[0] 0x1F 0
12747   17806 [main] strace 1005 spawn_guts: waitbuf[1] 0x12 = 0
