Changelog: omit
Docs: omit

Note.- Not to be merged, changes (if needed) should go through #4917.

This PR evaluates the examples introduced in #5074 with the new behavior given the compiler.cppstd subsetting: it is introducing the default value always. Tries to validate (or not) this comment: #4917 (comment)

It fails as expected, only clang in Mac (why not in Linux?) using the CompilerArgsGenerator:

> clang -x c main.c -m64 -O3 -DNDEBUG -stdlib=libc++ -std=gnu++98 -o app

error: invalid argument '-std=gnu++98' not allowed with 'C/ObjC'
