New AIX bootstrap failure in libstdc++

[David Edelsohn <dje at watson dot ibm dot com>]

	With this morning's update, GCC no longer bootstraps on AIX.  I
see the same error that Andreas reports for Darwin.  AIX bootstrapped
correctly with an update last night which included Richard's varasm.c that
broke other platforms because of VAR_DECL.  This mornings update included
Richard's fix for that earlier patch.  That patch and Kevin's dbxout.c
patch are the few additional patches since the lsat successful bootstrap.
