gcc 4.2.0 build fails on mac os 10.4.9, intel, /usr/bin/libtool: fatal error in ld64

["dan hitt" <dan dot hitt at gmail dot com>]

Hi,

I'm attempting to build gcc 4.2.0 on an intel mac, os
version 10.4.9.

I have a very plain setup, no fink or other software
installed (except for the developer tools).

I ran configure with no arguments (except for the
installation path).  Per standard, i configured in
an empty directory (not the source directory).

I ran make, and it chugged along producing about
30,000 lines of output before it conked out with the
error
  /usr/bin/libtool: fatal error in ld64

This was in stage 3, working on libgcj.la (5 layers
deep).  The exact command is very long, but
starts out
  ......bld/0/./gcc/xgcc -shared-libgcc........
and ends up
  .......-compatibility_version 9 -current_version 9.0

So
 (1) is this a issue?

[I suppose that it actually is an issue, because ideally
shouldn't configure detect a problem and say "Oh, your
version of libtool isn't up to snuff, you should use
a better one" or something like that?]

(2) Any recommendations on the next step i should
take?

Thanks in advance for any info, corrections, suggestions,
pointers to faqs, etc.
