[C++] mensagens de aviso ao compilar

[diarmaint 19]

Galera, estou com as seguintes mensagens ao compilar um tfs 0.4 no ubuntu .

o processo termina tudo correto, mas por ser tantas mensagens de aviso, não sei se isso pode prejudicar o servidor de alguma forma, como lags etc..

Isso afeta em algo o servidor?

é normal? teria uma forma de resolver?

provavelmente as funções irão dar erro de execução.

A forma de resolver seria refazer os códigos com falha.
