Also -ansi and -pedantic if you're aiming at the C89 standard for some reason, it's great to look in the gcc manpage and see all the little flags that are around. I don't often like -Werror since it can interrupt my flow. If I'm testing runtime correctness, and something like "suggest parentheses around assignment used as truth value" pops up when that was intentional, I don't want to make the context switch to go back and fix it and recompile before context switching again back to test whatever runtime correctness I was aiming for. I'll fix it later. Philosophically, -Werror assumes I'm the type of person who ignores warnings completely for the duration of a project, and will stop you from ignoring them in the first place even if there may be reasons to; I don't think most people are that way.
