No Shit.

An opinionated subset of -Wall -Wextra

warning: adding 'int' to a string does not append to the string

No shit.

This set of flags is designed for compiling C under GCC and Clang. Our guiding principle is to silence any warning aimed at flagging otherwise valid and reasonable code that possibly contains a programmer error. Warnings that flag invalid or unreasonable code, such as -Wunsequenced and -Wpointer-compare, are not silenced.

Note that some warnings, such as -Wunused and -Wswitch and -Wenum-compare, could have been silenced but currently are not.
