RFA - C++ new initializers

[Nathan Sidwell]

Hi,
this relates to bug 1654 which gives an ICE on `incorrect' use of
G++'s new initializer extension.

g++ allows one to say things like
	new int = 5;
	new int[4] = {1, 2, 3, 4};
However, that's giving an ICE in 1654's case, because it is saying
	ContinuedFraction cf = {4, new BigInt = {2, 1, 4, 3}};

I can't see any documentation on this extension in extend.texi. I had
thought that maybe it was restricted to pod types, but testcase
g++.robertl/eb63.C indicates otherwise.

We also allow non-default initialization of array members like
	new int[5] (3)

What to do.
a) remove the extensions.
b) deprecate the extensions.
c) keep them for non-pod types  (and document them)
d) get them working for pod types too.

My preference is a or b.

comments?
