XEmacs (I think from 20.4 on) now has a configuration option
(`--gung-ho', aka indexed lrecord type and minimal tagbits) that
moves those flags down to the low two bits, which also gives 30 bit
integers. Kyle Jones made those changes; I believe the work was done
in preparation for a new dumper of some sort. I know very little
about this.
(insert (format "\n%s\n" (- (expt 2 30) 1)))
