config.sub was mapping all single-component shorthands matching the shell glob `dpx2*` to ‘m68k-bull-sysv3’, which is incorrect. Of the four different machines once manufactured by Groupe Bull whose model number can be abbreviated ‘dpx2something’, only two were m68k-based: the DPX/2-200 and DPX/2-300. The DPX/2-100, on the other hand, had an i386 CPU. And the DPX/20 was a completely different beast, released years later and based on the POWER architecture. I’ve chosen to keep making ‘dpx2’ map to ‘m68k-bull-sysv3’ as the DPX/2-200 and /2-300 seem to have been the most widely used. config.sub now understands ‘dpx2100’, ‘dpx2200’, and ‘dpx2300’ as shorthands for ‘i386-bull-sysv3’, ‘m68k-bull-sysv3’, and ‘m68k-bull-sysv3’ respectively. It also accepts ‘dpx21xx’, ‘dpx22xx’, and ‘dpx22xx’ as equivalent to these, but no other variations; in particular, ‘dpx2xxx’, which was in the test suite, no longer works, as it is ambiguous. (As far as I can tell, there weren’t actually any submodels of any of these systems, so I could be persuaded to remove the …xx aliases. I kept them mainly because of the test suite formerly testing dpx2xxx.) Finally ‘dpx20’ now maps to ‘rs6000-bull-bosx’. Both the ‘rs6000’ and ‘bosx’ components of this name are debatable, but I *think* it is what config.guess would do on this machine.
