 The script under test is created on the editor working on Windows 
(Hidemaru), so that no additional CR is found in the script. 
I checked it by using od.

 No difference is made on the text mount directory, igncr is applied 
or not, which means the script doesn't work on text mount directory 
regardeless of whether igncr is specified or not, like that:

--- 8< ------ 8< ------ 8< ------ 8< ------ 8< ---
$ LANG=C bash -o igncr test.sh
hoge
test.sh: line 3: fuga: command not found
test.sh: line 4: piyo: command not found
test.sh: line 5: o: command not found
test.sh: line 6: ho: command not found
test.sh: line 7: cho: command not found
--- 8< ------ 8< ------ 8< ------ 8< ------ 8< ---

 On binary mount directory without igncr, CRs are recognized as 
a part of a command name by bash, as usual.

 I've attached the script.

 I'm sorry that I lost your original message, I'm writing this 
from the message which is gotten from cygwin mailing list 
web interface. This does not have the message ID to use threading 
the messages, so I reply to my own message to continue the thread.

Best Regards.
