$description = "This script tests to make sure that GNU Make looks for
default makefiles in the correct order: GNUmakefile, makefile, Makefile.

On non UNIX platforms, notably Microsoft OS's filenames may be case
insensitive (e.g. makefile can match Makefile). So on these systems we
check only the order GNUmakefile, Makefile.

Note that this test removes its makefiles on success even if \"--keep\" is
in effect.
