New Revision: 227760

URL: https://gcc.gnu.org/viewcvs?rev=227760&root=gcc&view=rev
Log:
The flag diagnostic_context::some_warnings_are_errors controls whether
to give the message "all warnings being treated as errors". However, when
warnings are buffered and then discarded, this flag is not reset. It turns
out we do not need this flag at all, since we already count explicitly how
many warnings were converted into errors, and this number is kept up to
date for the buffered diagnostics used by Fortran.
