Bash Version: 3.1
Patch Level: 14
Release Status: release

Description:
        Aliases don't work correctly in command substitution when in 
        noninteractive mode. They do work when in interactive mode.
Repeat-By:
        The following script illustrates the problem:

        #!/bin/bash
        alias foo=echo
        echo `foo hi`
        echo $(foo hi)

        When I call it, I get a "foo: command not found" error. However, if I
        insert those commands manually in my shell, they work as expected.
