Better would be GNAT on Lynx.

Lynx (http://lynuxworks.com) is a true real-time system, with a POSIX
interface. AdaCore offers full support for this combination.

I use it at work, but on x86 targets. Lynx is not as nice for running
development tools (such as Emacs) as Linux, but it is nicely
real-time. Writing device drivers is easier in Lynx than Linux. And
the AdaCore support is wonderful.

Hmm. I run Emacs on Lynx on x86; Lynuxworks offers a "self-targeted"
gcc for that CPU. I think they don't offer a self-targetd CPU for
PowerPC; you have to use cross target. I don't know why; you should
ask AdaCore and/or Lynx.

In any case, GNAT + Lynx on PowerPC is still more real-time, and more
supported, than GNAT + Linux on PowerPC.
