Frankly, given the option to tie our release process to Apple or stop
providing ready-made Apple installers, there is not much of a choice
here.  We have too few people able to maintain GUB anyway.  A licensing
restriction of running GUB only on Apple hardware would be in conflict
with the many GPLed third-party components of it even if we could
convince Jan to give us permission.

Special permissions that will not extend to using GCC from GUB for other
purposes would not allow us to redistribute GCC.

I am afraid that this is so far in Apple's GPL war zone that we cannot
skirt the topic.  We can still refer people to Apple communities doing
their own non-cross compilation.

The other option is ditching LilyPad and doing a Darwin-only version of
LilyPond, assuming that we can do this with suitably free components.
