Esta mensagem é um erro ou um aviso? O que posso fazer para corrigir isso?

Não é um erro nem um aviso - é odetalhadosaída, incluindo o caminho de pesquisa do pré-processador. De man cpp
:
-v Verbose mode. Print out GNU CPP's version number at the beginning
of execution, and report the final form of the include path.
Se você quiser apenas as informações da versão, você pode usar cpp --version
:
-version
--version
Print out GNU CPP's version number. With one dash, proceed to
preprocess as normal. With two dashes, exit immediately.
