I think you need __attribute((aligned(16))) on the original forward declared
class too.
As stated that does, indeed, fix it.
So, ok, let's say previous versions were too permissive, then, the
pragma GCC optimize or function __attribute__'s can be used
to request specific optimization levels or -f type command
line arguments.
I would like to be able to turn off debugging symbols
as well. The equivalent of the -g0 command line option.
It might be useful to be able to selectively turn

Note that certainly we don't want to use C++0x stuff here. Also, one thing at a

another time.
