I have a file with pragmas suppressing warnings. For example:
#pragma GCC diagnostic ignored "-Wregister"
#pragma clang diagnostic ignored "-Wlogical-op-parentheses"

The first, I believe, is to suppress use of the keyword "register" in Flex generated code. The second is for Clang promoting programming in the style of Pascal, which did not have enough of grammar precedences.
