I hope this is the right product - please move as needed.

I want to build llvm-gcc-4.2 with GCC 4.3.1 AMD64. I ran

CXX=`which g++` ../../src/llvm-gcc-4.2_svn/configure --prefix=/build/axel/local
--enable-checking --program-prefix=llvm-
--enable-llvm=/build/axel/build/llvm/obj/llvm-configure
--enable-languages=c,c++ --disable-bootstrap


Compilation with
  make LLVM_VERSION_INFO=trunk-20081001-axel
stops here:

What am I doing wrong? Or could these functions' declarations be added?
