[c++] bug 2628 and new

[Nathan Sidwell]

hi,
bug 2628 concerns operator new indicating failure by returning NULL, and
-fno-exceptions.

The user had turned off exceptions with -fno-exceptions and expected
operator new to indicate failure by returning NULL. What should the
expected behaviour be?

1) we could turn on -fcheck-new when -fno-exceptions is enabled. The
user must replace the system provided operator new.
2) we could call operator new (std::nothrow) in place of operator new ().
3) we could issue a diagnostic when -fno-exceptions is enabled an
operator new is called (and any other throw expression?)

thoughts?
