Yes, I made it gcc specific, also added a similar fix for is_union, but not
for has_trivial_copy which also produces these warnings.  Fixes will be in
cvs towards the weekend - when I get my cvs access up again (I only have
limited mail access at present).

Not quite - the fix is required if you can't pass non-copyable types through
is_convertible, and that is still true for some compilers unfortunately,
even if this has been fixed for most of them...
