On some CPUs, they are nothing but aliases.  On other targets, the RTEMS
patch gives you significant benefits.  For example, on the i386 and
PowerPC,
you get thread-aware remote debugging across Ethernet.  On some CPUs,
you
get support for additional ROM monitors (167bug, *PPCbug, Dink32,
PPC2Dink32,
and soon 162bug).  You also get some patches to simulators.
