gcc 3.0 branch fails on libstdc++

[Matthew Conway <matt_conway at i2 dot com>]

I'm having trouble compiling the gcc 3.0 branch (CVS dated 4/11/2001)
under AIX 4.3.3 using the redhat gnupro assembler (suggested by David
Edelsohn).  The compiler builds fine, but libstdc++ fails during
linking with the errors shown at the end of this message (In short,
unresolved std::errno from locale-inst.o).  By the way, it takes a
REALLY long time for the libstdc++ configure, on the order of 8-10
hours for the entire compile (compiler itself takes at most 2 hours),
and this on a 4-way 220Mhz PowerPC_RS64-III machine with 4 gig of RAM.

If this is already fixed on the main branch, is there an easy way I
can get those changes into the version I am trying to compile
(preferably without having to reconfigure)?  Thanks,

Matt

Not sure if this helps, but here is the relevant snippet from the '-E'
