About `cl-load-time-value'

[Xue Fuqiao]

In the trunk version of (info "(cl) Time of Evaluation"):

     In a compiled file, `cl-load-time-value' arranges for FORM to be
     evaluated when the `.elc' file is loaded and then used as if it
     were a quoted constant.  In code compiled by `byte-compile' rather
     than `byte-compile-file', the effect is identical to
     `eval-when-compile'.

Why is the code compiled by `byte-compile' and `byte-compile-file'
being treated different?  Can anybody help?  Thanks.
