glibc 2.7 fails to build with gcc 4.3.1 (error messages given below).
Investigating the error, I stumbled upon PR 36111. Applying the patch from
http://gcc.gnu.org/viewcvs/trunk/gcc/ChangeLog?view=markup&pathrev=135221
makes gcc 4.3.1 build glibc OK (and everything else that I tried).
Maybe someone could comment on whether this is the correct way of fixing it.
