- Authentication-results: sourceware.org; auth=none
When GCC defaults to C++14, it gives -Wsized-deallocation warnings for
the non-sized operator deletes. We dealt with this for the sized ones
by passing -Wno-sized-deallocation on the command line, but using
#pragma GCC diagnostic seems cleaner to me.
Applying to trunk.

* libsupc++/del_opv.cc: Suppress -Wsized-deallocation.
* libsupc++/del_op.cc: Likewise.
