OK, here is a new patch; the diffs are against the CVS repository.

Note that this is only for the HP PA-RISC part; I have included a new
ChangeLog entry to reflect this.  Please let me know if there are any
further problems with the patch. 

Now, some other questions regarding the guessed values that my previous
patch solved differently.
 
 * On cygwin32 (or mingw32) config.guess always returns
   `i386-pc-cygwin32'. I see two problems with this: first, it does not
   differentiate between different processor types, and second, it does
   not differentiate between Windows 95 and Windows NT versions.  Since
   several other platforms do not force processor type to `i386', why
   does that happen on Windows?  We would certainly want to optimise the
   code to take advantage of pentium instructions (or even ppro).

   The second may not be important for GCC itself, but I can imagine it
   makes difference for other packages (it certainly does for us).  The
   root of the problem is that the system API is different on NT and 95,
   so applications configured and built for NT will not necessarily run on
   95 and vice versa.  It would be nice to be able to differentiate
   these different binaries.

   (My previous patch returned strings such as `i686-cygwin32-winnt4.0'.)

 * On LynxOS, both RS6000 and PowerPC variants are folded to rs6000-*.
   I know the processors are supposedly similar, but are they really
   that similar?  For all that I know, people here are using PPC
   boards running LynxOS, and so far I have used powerpc-* as the
   configuration string.  I can rename things to rs6000-* if that
   is known to work.  And yes, I have absolutely no clue about this
   platform otherwise---I just need to support gcc on it.

	* config.guess: more accurate determination of HP PA-RISC
	processor types for 9000/[678]?? series machines.

	* config.sub: ditto.
