OpenBLAS common.h fails to compile when building BVLC Caffe

[Prune]

I don't understand why OpenBLAS common.h does not already have its dependencies included.
I'd appreciate a pointer to what I've missed.

I downloaded and built OpenBLAS per instructions, and it appears that it completed properly.  However, when I try to build BVLC Caffe on it, I get a litany of failures.
Here are the first 35 lines of over 500.  It appears that there's a C / C++ confusion, perhaps?

Fixed.  I'm not sure what caused the problem, but the fourth attempt to build and use finally worked.

Even I get this error. How did you fix it?
