[LLVMdev] Bootstrapping llvm-gcc4 on Mingw

[Anton Korobeynikov]

Hello, Everyone.

I'm currently trying to bootstrap llvm-gcc4 on mingw32 platform.
Everything (except some small fixes) seems to be fine: stage1 finished
successfully. I'm linking with debug variant of LLVM, since linker bug
prevents release builds.

Unfortunately, stage2 failes immediately with this cryptic message:

Does anybody have idea, why does this error might occur? I can supply
any needed information (such as -save-temps output, etc).
