Again... really? I have code using '= default' that sometimes¹ is built
on GCC *4.4*. '= delete' seems to be accepted also. (Now... it may be
that '= default' is actually broken, i.e. generates bad code, but based
on a very simple test I just whipped up, '= delete' at least seems to
work. This is with gcc44-c++-4.4.7-1.el5.)

(¹ Well... it's 'intended to work on GCC 4.4' and does occasionally get
tested, but maybe not often or - as far as verifying that it actually
runs correctly - well.)

Did it get broken by 4.6 or something like that?

Ah... don't use it, hadn't paid attention or noticed :-).
