You told it you want C11.
$ gcc -std=c11 -c str.c
But you didn't tell it to warn about non-conforming code.
Moreover, you asked it to warn about things that may or may not have an

A good idea.
Thanks!

Apropos of help from the compiler, I normally run gcc via this script

BTW, just as a curiosity, I'm facing a code base full of unterminated strings,
and the good thing is it uses u_char* everywhere. So I'll do some small change
to make sure I know which strings are terminated by starting to use char* on
those. Then, the compiler will warn me if I mix them at any

None of this surprises me but it reminds me of how I described C to
my older son who is learning computer science.
C is sort of like driving a sports car on a narrow mountain road with
no guard rails. If you like to text while you drive, C is not for you.
If you can't keep your eyes on the road,
