It's kind of re-iterating the command line options, that the user will

It was there in GCC 4.1, maybe earlier, I didn't check.
However, coming back to my query: Is there a need to remind the user
that warnings on the build are being treated as errors? Is this a
special case because it would cause the build to stop?
For example: -Wall means I see "control reaches end of non-void
function" messages, but doesn't output "cc1.exe: all warnings turned on"
I'd thought because the previous line of output said "gcc -Werror -Wall -o
main main.c", the options clear.
Not if you run "make" and it doesn't echo the compiler command, or run
the compiler from an IDE, or anything else which shows the errors but
not the command.
I would have though that it's not GCC's responsibility to echo the
options passed to it. Like the IDE example, the IDE can inform the user
of what compiler options are in use; I don't see why GCC can't keep
quiet about -Werror.
Best regards, Jon
