Subject: 25.0.50; byte compiler confuses compilation-mode
Date: Wed, 05 Nov 2014 14:52:49 -0700

I ran the byte compiler via M-x compile.
I got some warnings like:

In toplevel form:
src/something.el:17:1:Warning: Unused lexical argument `obj'

compilation-mode things that the line "In toplevel form:" is some sort
of error.  The words "toplevel form" are red.  If I next-error it says:

    Find this error in (default toplevel form): 

This also happens for the text "In provide:", also emitted by the byte
compiler.

This makes compilation mode harder to use.

(I'm going through old bug reports that unfortunately have not received
any responses yet.)

I see there's been some work in this area in the intervening years -- do
you still see this problem?  If so, do you have a test case?

I've forgotten what code I was compiling.  Probably it was complicated &
that is why I didn't send it in.

I guess you can close this.
