Apparently -Wall and -Wextra is believed to be enough; not sure what to expect with -Weverything but I'm intrigued :)

EDIT: interesting indeed. Thanks for the pointer!

Yeah, as has been mentioned many times before `-Wall -Wextra` leaves out a ton of warnings/errors (despite what the names imply). `-Weverything` is an alias for enabling all warnings. I find it much better practice to enable all warnings and then selectively disable the ones which warn me about things I have done intentionally through pragmas in the code.

I like to use -Wpedantic for my own projects to keep the code clean and it helped my well. Its not included in -Wall and -Wextra.
