[LLVMdev] Compile dll on Mingw

[yuan zheng]

Hi, NAKAMURA Takumi

According to your prompt, I'm very glad that it can generate llvm-2.8svn.dll
!

But there is still some compatibility problem between llvm-2.8
and our project. If we use llvm-2.6, there is no problem.

I would study the code of LLVM to find the difference recently,
and I will contact you if I make some progress.

Thanks for your enthusiastic  and timely answer.

Thanks,
yuanzheng.
