CPUID should be precompiled. So this does not work. If GLAS do 
not need anything but CPUID, what the reason to depend on 
DRuntime?

Please stop to force me to use DRuntime because you think it is 
better for Mir projects. This looks like DRuntime religion.

A betterC library can be used with DRuntime. So I do not force 
anyone to drop DRuntime. Please do not force me to use it.

GLAS already works without DRuntime and I am happy about that.
