No, it means that is prohibited by Apple to use Xcode for compiling
LilyPond with GUB on non-Apple hardware.  This is a restriction
incompatible with the GPLv3 license GUB is under, so current Xcode
versions cannot be made a part of GUB.

It does not preclude someone else compiling LilyPond with Xcode under
whatever native platform they want, but it means that MacOSX compilation
cannot be integrated into GUB and consequently our release process using
the current Xcode SDK.

We build our Windows binaries with GUB and upload them essentially
untested.  That may seem surprising, but once stuff makes it through
GUB, it is quite rare that it is inoperative to any significant degree.
