Please show the exact file you used as the compilation command,
because I cannot reproduce this with a few programs I tried, see
below.

I tried this with several commands and it worked for me with all of
them.  Here are the commands I tried:

  . sleep 20
  . ping -t SOME-EXISTING-SITE
  . a batch file which does this:

     @echo off
     :again
     ping -n 1 SOME-EXISTING-SITE
     sleep 60s
     goto again

In all three cases, I get the same expected result in the
*compilation* buffer:

  Compilation interrupt at Sun Jun 30 11:58:49, duration 4.44 s

(with the time and the "duration" values changing as appropriate).

So I suspect the problem is with some specific command/program or a
group of programs that behave in a specific way.  Thus the request to
show which program you used in your case.

(Just to be sure: you typed "C-c C-k" from the *compilation* buffer,
yes?  If you want to interrupt the compilation process from another
buffer, you need to invoke kill-compilation by name, via M-x.)

Not clear yet; more info is needed.
