Yes, much better.

I belive that both of these `= ...' can be dropped - since info.osabi is 
explicitly initialized, no magic values are needed.  This is also more 
consistent with it being a named enum.

Hmm, why was the enum to a new file?  Ah!  Ulgh, "gdbarch.h" needs the 
definition :-/  Rather than create a new file, just move the enum to 
"defs.h".  This is consistent with other, similar, enums solved the 
problem.  It also stops me thinking that "osabi.h" should include 
"osabi-list.h" (nb, s/_/-/) :-)

enjoy,
Andrew
