Thanks, but this fix wasn't that hard...  I had a little trouble with  
the testing
due to other issues.  Many GCC bugs are much harder.  Things are easy
when the compilation bug is clear.

I integrated Guy's patch into debian 2.13-10 today and I was going to do
a build, but then I discovered it builds using 4.4.  So, I patched 4.4  
with the
above change, and will rebuild 2.13 when it's done.  Hopefully, this  
will
fix the udev bug which is blocking many python builds.  I'm interested  
to
see if the glibc testsuite results will be better.

It's a bit unclear how extensively TLS variables are used, but maybe  
fixing
this will make it easier to resolve the remaining pthread bugs.

I've been wondering how much is left to install to glibc head?

Dave
