Cannot redirect to STDIN in a shell script - Shell Programming and Scripting

I am unable to use STDIn redirection with < (commands)
When I do the following, both approaches work and give the same results:

1.

Code:

$ printf "aaa\nbbb\n" > file1
$ printf "111\n222\n" > file2
$ cat file1 file2
aaa
bbb
111
222

2.

Code:

$ cat <(printf "aaa\nbbb\n") <(printf "111\n222\n")
aaa
bbb
111
222

However, the second approach won't work when I put in in a script.

I am using Cygwin1.5.25-15

Any clue?
