My patch could handle that.  But I don't take too much time on how to 
print them. So the output is like this:

(gdb) ptype z
type = Type bar
      Type foo
      real*4 a
End type x
      real*4 y
End type
(gdb) p z
$3 = { { 1}, 1.20000005}
(gdb)

Do you have thought on how to print that kind of embedded type? 

In fact, that patch is only a begining.  I just want to use that as a 
strawman to solicit some comments, so that I can made it better to be 
acceptable. To support derived type completely, 'p z%y' is also needed.
But I want to see how are you thinking on this patch first?  Especially 
from GDB community.  :-)  Anyway, my patch needed to be get into gdb 
source to support that.  :-)


Any comment from gdb maintainers?  Daniel, any thought on this patch?
