Unfortunately I've never been able to build eglibc with the supposed

BTW, how did you successfully build it? you said you build a good part
of unstable, I would like to do the same and maybe upload some key

The dependency issues have been somewhat tricky. I recall that I did my initial 2.13 build with my own tool chain builds (binutils and gcc). I wanted to ensure that I had the binutils fix for non equivalent aliases. There were also some compiler
fixes that I wanted.

Carlos sent me his current glibc patch set and I integrated them into the 2.13-10 patches. I could send you my current two patches tonight. Carlos also has these updates. This wasn't completely straight forward as there were some conflicts
with the existing patch set.  The main goal was to fix a bug in thread stack
allocation (tst-timer1?).

I used 2.13-10 as my starting source for applying Carlos' changes. I had built 2.13-13 previously, but I removed the source. I had tried building and installing 2.13-14. However, it wouldn't install without breaking my installed version of perl.
So, I had to go back to 2.13-10.

Once I had the glibc multiarch support installed, then I built the latest unstable versions of binutils, gcc-4.4, gnat-4.4, gcj-4.4, gcc-4.5, gcc-4.6, etc. I'm still using
gcc-4.4 as my default.

Next, I had to update perl and python. This involved updating a bunch of libraries. There was more than one dependency loop where I had to force installation of a library because I needed it to build the library that the installation depended on.

Part of the problem is I was starting from a system updated to testing/unstable.
Many of the "-dev" packages for libraries had disappeared as newer versions
were built and uploaded to the servers. I couldn't really go back without breaking
a huge amount of stuff.

So, I just plunged forward. It's not really possible to support GCC without having
the new stuff in unstable.

I have kept all my .deb files and can provide them if needed.

I had hoped that we would get a buildd going by now. If we wait much longer,
the dependencies will be a killer.

Based on my experience, a fair number of packages need some manual
intervention to get them to build. For example, with glibc, it probably is necessary to disable testsuite checking. With perl and python, it may be necessary to manually
kill tests that  hang, etc.
