Ahh, OK, if you did so, you won't have any place to hook the "only
on msys do this" trick into.

It somehow feels somewhat confusing that we define a sub with the
same name as the system one, while not overriding it entirely but
delegate back to the system one.  I am debating myself if it is more
obvious if it is done this way:

        use File::Spec::Functions qw(file_name_is_absolute);
        if ($^O eq 'msys') {
                sub file_name_is_absolute {
                	return $_[0] =~ /^\// || $_[0] =~ /^[A-Z]:/i;
                }
        }
