> The common header file for vectorization is included in multiple files, and so
> must use macros for the current compilation unit, rather than the compiler-
> capability flag set for the whole driver. With the current, incorrect, macro, the
> AVX512 or AVX2 flags may be set when compiling up SSE code, leading to
> compilation errors. Changing from "CC_AVX*_SUPPORT"
> to the compiler-defined "__AVX*__" macros fixes this issue.
