bug#12473: 24.2.50; Eager macro-expansion failure: (void-function byte-compile-log-warning)

[Drew Adams]

I am now getting this when I start Emacs (with my setup) - I see this at
the top of *Messages*:
 
Eager macro-expansion failure: (void-function byte-compile-log-warning)
Loading delsel...done
Eager macro-expansion failure: (void-function byte-compile-log-warning)

I have no idea what that means or what I should do about this, if
anything.
 
This is new.  I do not see it in a build from 2012-09-03.
