The error comes up, when xgcc, in the object directory, compiles the
libgcc/unwind-dw2.c file from the source directory into the object
directory. "/usr/local/zich" is the objdir ; "usr/local/gcc-4.7.0" the
srcdir.
Maybe i setup something wrong on the configuration. But the libpthread.so
library seems to work fine when compiling code under gcc 4.6.1 with the
"-phtread" compiler option. I think this option should somehow be invoked
for the make scripts of gcc 4.7.0. But i don't know how and where to set it.

I want to build the compiler on a i686 architecture with
Linux-3.0.0-19-generic kernel and Ubuntu 11.10 (oneiric).
