You also told me glibc 2.5 *cannot* compile without TLS support and that is *critical* for the m68k port. > - hurd-i386 > It has TLS support in binutils, gcc, and glibc, but it is currently > disabled in glibc (if I remember correctly, it is due to kernel > freeze with TLS activated). > > Until now (and for Etch), it was not really a problem for an > architecture to not have TLS support.

Do you mean a Debian maintainer or an upstream maintainer for m68k glibc? If only I had the time... Several people have talked about TLS support for m68k, but it seems nobody has done it so far. I replied to your post, because it seems to have been ignored and I felt a bit ashamed of that. ;) Anyway, I will try to look in the issue and contact the people who spoke about it earlier on this list.
