[wp-hackers] hook availability

[Amit Gupta]

is there a way by which a plugin can check whether a hook is available 
or not?
I mean something along the lines of PHP's function_exists() function
which I think would go quite a bit in helping plugin authors create
backward compatible plugins and/or check whether the hook/filter
they want exists or not & display appropriate message to the
user incase the hook/filter is not available.
