This may be 2 unrelat= ed problems.  However, I'll report them with this one email since the = reproduction requires the same steps.

I have a Makefile whi= ch builds a library out of a large number of object files.  The compil= ation command that is output by make is 2826 chars long.  Unfortunatel= y, Emacs hangs part-way through inserting the command into the *compilation= * window and then leaves point part-way through the line even though compil= ation-scroll-output it t.

You will need a Makef= ile that is going to output a long line.  This works for me:

all:
        @echo the very long line copied from my real makefil= e

Now emacs -Q and eval= in *scratch*

(setq compilation-scr= oll-output t)
(setq special-displa= y-frame-alist nil)
