Because it didn't work. This:
(fboundp ',name))
was expanded by `macroexpand' to:
(fboundp ...)) ;; Exactly as shown.
Using `quote' like this:
(fboundp (quote ,name)))
I got the same result.

Then I should have tested the macro with `macroexpand-all' instead of
`macroexpand'. However, I've tried using the macro, and it seemed to
work, albeit it choked on the unquoted symbol passed to `fboundp'.

`defun' is not a function, it's a macro (defined in C source code).
Thanks for answering.
