Hmm... those files that have already been compiled with earlier Emacsen
will not keep this var up-to-date, so it can't be used reliably.
Also, I wonder why we need this to be a variable.

Can't we have an `enabled-minor-modes` function instead, which can simply
loop through `minor-mode-list` and see which ones are enabled?

For global minor modes, this will adjust the list for the buffer that
happens to be current when the mode is changed, but it won't affect all
other buffers's lists.
