Does it also deal with the lib/Transforms/Hello build failure ?

Many thanks,

I had to hand modify the code as it did not seem to want to work as a patch.

However, it does not deal with the LLVMHello.dll problem. Here's what I am
getting :-

Nick, could you lease give me a list of all the LTO revision/patches so that
I may backpeddle and try to get to the bottom of this.

[LLVMdev] -fPIC warning on every compile on Cygwin

Please try this patch. I tried to copy exactly what libtool would do on
