    I believe replacing (and (boundp 'foo) foo) with (if (boundp 'foo) foo)
    is a better choice because it removes the warning wihtout cluttering the
    code and without introducing compatibility problems with older Emacsen.

Why not extend that compiler feature to handle `and' as well as `if'?
This construction is common enough.
