Fix unused variable treatment (#139)

Browse Source 
Right now our CMake infra specifies -Wno-unused only for GCC builds, but Makefile specifies it for all builds.
The intent has been to use it just for GCC, so we now do that by detecting the compiler version - this should
equalize the behavior across different types of builds.

Separately, latest version of clang appears to expose an unused variable that clang-10 was okay with, so fix that. (change from upstream)
