I am getting an error building svn llvm-gcc on Cygwin :-

/home/ang/build/llvm-gcc/./gcc/xgcc -B/home/ang/build/llvm-gcc/./gcc/
m-gcc/i686-pc-cygwin/bin/ -B/usr/llvm-gcc/i686-pc-cygwin/lib/ -isystem

make[4]: *** [libgcc/./_popcountsi2.o] Error 1
make[4]: Leaving directory `/home/ang/build/llvm-gcc/gcc'
make[3]: *** [libgcc.a] Error 2

I have tried with gcc-4.2.4 and gcc-4.2.1 and it fails in exactly the same
place in libgcc.

Anyone got any pointers ?

Many thanks in advance,
