> Macro __SIZEOF_LONG__ is not standardized and MSVC does not define it.

> ../lib/mldev/mldev_utils_scalar.c(478): error C2051:

> '__SIZEOF_LONG__': undeclared identifier
> ../lib/mldev/mldev_utils_scalar_bfloat16.c(49): error C2051:

> The fix is to define __SIZEOF_LONG__ in a common header when
