 Go ahead and close the PR.  I have updated my gcc 3.x arm-netbsdelf
 config with recent changes in the NetBSD tree, and successfully built
 the library I previously had trouble with (libcrypt) without any trouble.
 
 I'll post about the arm-netbsdelf config to gcc-patches separately.
 
 Thanks!

 	1) I was waiting for the NetBSD ARM ELF ABI to be fleshed
 	   out before submitting the configuration.  Now that it's
 	   been worked out for the upcoming NetBSD release, I'll
 	   update it and submit it.
 
 	2) Ok, I'll try again and let you know.

State-Changed-Why:
    Two points:
    
    1) The arm-netbsdelf configuration hasn't been contributed yet. It would
    be good if someone could arrange that.
    2) I've tried this on an arm-elf cross compiler and it compiles
    without problems.  I suspect, though can't prove that the underlying
    bug is now fixed.
