That's what I thought.  Which means that I still need that code to let Icicles
users optionally byte-compile the defuns in the `eval-after-load' contexts.

I guess the bug has to do with why it thinks it cannot do its job here.  Unless
there is some bug in my code that makes compilation impossible where it should
otherwise be possible.  Can you tell by looking at the code I sent?  Or do you
think there is a byte-compiler bug here?

Since older byte-compiler versions apparently were silent when they could not
compile, I don't know whether they were able to compile or not in this context.

Hence the value of the new error.  But I wonder whether it shouldn't be (perhaps
it already is?) configurable: e.g., ignore, warning message only, raise error.
