QUESTIONS:

1) What is the difference between 'New Architectures' and 'New Targets'?
   Has there realy only be one of each sense 6.0?

2) These seem to removed in the given release, but not obsoleted first.
   Is this correct? 
	386BSD, 6.1
	SGI Iris (MIPS) running Irix V3, 6.1
	SGI Irix-4.x, 6.1
	SPARC running LynxOS, 6.1
	SPARC running SunOS 4, 6.1
	SunOS 4, 6.1
	VxWorks and XDR protocol, 6.4

3) These seem to have be obsoleted in the given release, but never
   removed.  Is this correct?
  	AT&T 3b1/Unix pc, 6.1
	Bull DPX2 (68k, SVR3), 6.1
	decstation, 6.1
	h8300, 6.3
	mn10300, 6.3
	Motorola 680x0 running LynxOS, 6.1
	riscos, 6.1 
	sh64, 6.3
	sonymips, 6.1
	sysv, 6.1
	v850, 6.3

4) What's up with 'Multi-arch'?  It is mentioned for 5.3 and 6.0, but
   not again. The 'V850' was multi-arched in 5.3 and then removed in
   6.0, without being    obsoleted first.  The 'NS32000' was
   multi-arched in 5.3 and then removed in 6.4, again without being
   obsoleted first.  Same thing with 'MCORE'.  Is this correct?

5) What is 'multi-arch'?  The 'set processor command can be used with
   PowerPC and the PowerPC 64-bit GDB can debug 64-bit or 32-bit 
   targets. (I have heard the latter refereed to as 'bi-arch').
