I am unaware of "(the hackery that Crosstool employs to handle) the 
libgcc_eh.a situation",

but I tried your patch on the same machine (see start of thread). Also thanks
for your DIY pointer BTW.

Several gcc/glibc combo's fail with different errors. Here is the output of:

gcc-3.4.3-glibc-2.3.3.dat

First, created crosstool with NPTL and Greg's patch as follows with this script.

---
#!/bin/bash

# Baseline crosstool (Dan Kegel)
wget -N http://www.kegel.com/crosstool/crosstool-0.35.tar.gz
wget -N http://www.kegel.com/crosstool/crosstool-0.35/contrib/crosstool-0.34-nptl.patch

# Greg Schafer <gschafer at zip dot com dot au>
wget -O crosstool-0.35-libgcc_eh.a.patch \
 "http://sources.redhat.com/ml/crossgcc/2005-06/txt00000.txt";

rm -rf crosstool-0.35
tar xzf crosstool-0.35.tar.gz
cd crosstool-0.35

# Apply NPTL patch
patch -p1 <../crosstool-0.34-nptl.patch
chmod +x ./demo-i686-nptl.sh

patch -p1 <../crosstool-0.35-libgcc_eh.a.patch
---

Then started off crosstool:

./demo-i686-nptl.sh

which fails as follows (interesting parts from tail of console log):

[...]
