Thanks for the comments. I understand the problems in implementing a compiler,
when this is also unclear in the language itself.

Whatever is decided related to this, it would probably be a good idea to give a
better error message. Right now, the error message is telling the user that the
operator new *with* an exception specifier doesn't have one and that they are
different, even though the two lines are exactly the same. It is a bit
confusing.

It would be good though to solve this in a way that both works with C++11 and
C++03 as it came up when compiling a piece of code that is used by multiple
compilers and by both language versions.
