Refs #193 . cblas: move #include out of extern "C" block.
...
Standard headers may contain C++ templates which are not permitted inside an
extern "C" block. This might be the case when we include <complex.h>.

cblas: typedef enums for improved compatibility with Intel MKL.
...
Netlib style:
enum CBLAS_XYZ {X=1, Y=2, Z=3};
Intel MKL style:
typedef enum {X=1, Y=2, Z=3} CBLAS_XYZ;
With this hybrid style, code written in the latter form won't need any
modifications to be built with OpenBLAS. This change should not affect existing
code, although a warning may be emitted for C code which does the following
(does not occur with C++):
typedef enum CBLAS_XYZ CBLAS_XYZ;
warning: redefinition of typedef 'CBLAS_XYZ' [-pedantic]

if we have 64 bit pointers we can't have a 32 bit cpu, so fall back to

causing it to use the uninitialized gotoblas_ATHLON

DYNAMIC_ARCH, NO_AFFINITY.
