Bash Version: 2.05b

Release Status: release
Description:
A syntax error with the expression : a**b**c
What is the associativity of the exponentiation operator ?
Repeat-By:
$ echo $((2**3**2))
bash: 2**3**2: syntax error in expression (error token is "**2")
I made the ** operator associative between bash-2.05b and bash-3.0,
but made it left associative like the rest of the binary operators.
It's more mathematically correct to make it right-associative, so
bash-3.1 will do that.
