Re: how to make gcc stop when there is a warning

Richard, if the documentation would have said explicitly that Werror
"makes warnings to prevent compilation", would you have understood it

One proposal:

-Werror  makes all warnings into errors, preventing compilation (see
also -Wfatal-errors).

Use -Werror -Wfatal-errors (that will stop after the first error, not
trying to continue).
