[Bug other/15378] New: -Werror should provide notification of why gcc is exiting

["ed at catmur dot co dot uk" <gcc-bugzilla at gcc dot gnu dot org>]

$ echo "main(){}" | gcc -x c - -Wall -Werror -o /dev/null
<stdin>:1: warning: return type defaults to `int'

gcc should output something like:
-Werror is set; regarding warnings as errors. Exiting.

This is necessary because when gcc is invoked from GNU make it is not always
clear what command-line arguments have been passed.
