I wouldn't spend time on this. If you want to print a message m4 crashed!! Please report this to bug-m4 according to the bug reporting instructions at http://..... then - regarding the mingw bug: it doesn't matter if there was a bit of extra output before it. - regarding the Cygwin bug, it means that for a few months Cygwin users won't see this friendly message. But this message was already absent for the last 10 years, not only on Cygwin, but on all platforms, and its absence did not cause much damage. Bruno
