in ways that are now deprecated.

it just needs to be optional to support Carbon GUIs. AU's can provide
no GUI, a Carbon GUI, or a Cocoa GUI (actually, they can supply
multiples of either of the last two). if they provide none, the AU
framework will cook up a Cocoa GUI for the plugin. more and more
plugins come with cocoa gui's but a few hang on to carbon (most are
changing). we can simply #ifdef the au_pluginui.mm source to drop
support for Carbon and ask for a generic GUI from the AU framework.

as noted above, not necessary. carbon-au-gui is the only issue.

my recommended approach:
cat /proc/cpuinfo | egrep '(model|MHz)'
model		: 10
model name	: AMD Phenom(tm) II X6 1090T Processor
cpu MHz		: 3612.568
model		: 10
model name	: AMD Phenom(tm) II X6 1090T Processor
cpu MHz		: 3612.568
model		: 10
model name	: AMD Phenom(tm) II X6 1090T Processor
cpu MHz		: 3612.568
model		: 10
model name	: AMD Phenom(tm) II X6 1090T Processor
cpu MHz		: 3612.568
model		: 10
model name	: AMD Phenom(tm) II X6 1090T Processor
cpu MHz		: 3612.568
model		: 10
model name	: AMD Phenom(tm) II X6 1090T Processor
cpu MHz		: 3612.568

gtk is already cocoa almost entirely. i've done some work on removing
the vestigial bits of carbon it still uses; what's left is "deprecated
but, uh ... yeah, we haven't come up with a replacement yet" by apple.

we shouldn't be using carbon at all in ardour, at least as an option
(--no-carbon or something)
