bug#34479: Incorrect classification of messages in compilation-mode buffer

[Tobias Bading]

I also discovered this bug a few days ago and came up with the same fix as 
Daniel. However, there’s a small mistake in his patch which results in 
incorrect error numbers in the mode line. The compilation--note-type call 
should look like this:

diff --git a/lisp/progmodes/compile.el b/lisp/progmodes/compile.el
index 146af5a..368b088 100644
--- a/lisp/progmodes/compile.el
+++ b/lisp/progmodes/compile.el

                                    (compilation-type type)
                                  (or type 2))))
