gcc3.0 branch problems under AIX

[David Edelsohn]

	Previously libstdc++-v3 produced with the AIX assembler would be
invalid, but would link.  Maybe some libtool changes have affected that so
it no longer links with the missin symbols.

	The problem has been the AIX assembler mis-assembling the symbol
table for ios.cc, locale-inst.cc, and string-inst.cc.  The current GNU
assembler snapshots have other problems, which should be fixed when the
Red Hat GNUPro changes are merged in.  As I mentioned, the GNUPro version
of gas, which is available from IBM through the AIX webpages
( http://www.ibm.com/servers/aix/products/aixos/linux/ ), should work.
