The diagnostic issue is trivial, just add a check for error_mark_node on the
return value of reshape_init_r, consistently with other calls.
However, I'm still analyzing whether we really want to reject. As data points,
ICC doesn't, even in strict mode; on the other hand Comeau rejects the
identifier "family" already...
Mark, do you have a quick opinion? Thanks in advance...

Does it reject the code because this form of member initializer (where you
name individual members) is really a C99 thing, not C++98?

Yes, designated initializers are of course a GNU extension to C++. I'm
surprised that icc accepts them in its strict mode.
In GNU C++, it makes sense for us to accept the same extensions that are
accepted in GNU C. So, if GCC accepts this, I think G++ should too. (I don't
know what the initialization of "id_struct" with "0" means, though; does it
only initialize the first element of id_struct::is_ip_addrs?) However, the GCC
and G++ code that processes initializers is, I think, mostly if not totally
distinct. So, it's likely that some significant work would need to be done to
handle this case.

Ok Mark, agreed, thanks. For the moment, I'm not going to work on this one and
I'm unassigning myself in order not to prevent anyone else quicker than me...

The infinite loop is gone in 4.5.x and current branches.
