Byte-compiling the following file:
(if (fboundp 'car)
(defalias 'mycar 'car)
(defun mycar (_l) (error "what")))
(defun foo ()
(mycar nil))
results in the byte compiler warning
Warning: the function `mycar' is not known to be defined.
However, the function is clearly always defined. Since this trick is
rather common, the byte compiler should know about it.
