Sorry I'm not sure about where to submit a patch.
http://savannah.gnu.org/projects/make/ ?
I keep on thinking about this since I saw your request Joachim!
Now maybe I can lay it to rest whether this is used or not.
As simple as possible I think.
Don't call to fatal so that easter egg error text is clear of adornment.
Exits using die(2) as fatal does.
Doesn't trigger action if -k (continue on error) is specified.
There's already a strcmp() call in remake.c (strncmp used for this patch).
There's already a getuid() call in misc.c, I think for all platforms.
Tested on linux, solaris and cygwin.
