Hi Anton,

Thanks for the advice, I will start from scratch again tomorrow :)

Anton,

Did a non parallel build of LLVM and have now got to stage 3 of llvm-gcc-4
:)

I will try again tomorrow with a parallel build again.

Thanks,

Now am getting stage 2 and stage 3 comparison failure  :(

make[2]: Entering directory `/home/ang/build/llvm-gcc'
make[3]: Entering directory `/home/ang/build/llvm-gcc'
rm -f stage_current
make[3]: Leaving directory `/home/ang/build/llvm-gcc'
Comparing stages 2 and 3

Bootstrap comparison failure!
./passes.o differs
make[2]: *** [compare] Error 1

make[1]: *** [stage3-bubble] Error 2
make[1]: Leaving directory `/home/ang/build/llvm-gcc'
make: *** [all] Error 2

Looks like LLVM and LLVM-GCC are broken again on Cygwin. I am using
GCC-4.2.2.
