Hello,
Part of the design of the compile features concept is that it may be used to
require compiler extensions. The extensions are enabled by default for GNU
and Clang - that is, the option -std=gnu++98 is implied. Passing -std=c++98
disables the extensions, as do other language standard

The user may still set it to FALSE explicitly in order to use a possible
non-extended compile option where available.
Fine with me. It matches the compiler behavior of having extensions
