Well, all I can say about it:
* i386-rtems-gcc-3.2-gnat compiles under Linux, but requires to you have
a native gcc-3.2-gnat installed.
* RTEMS's gnat wrappers have been merged into RTEMS in recent snapshots.
* RTEMS's gnat testsuite has been merged into RTEMS, but is still
problematic (It hardly compiles and probably has never been run on
actual HW, yet, AFAICT).

Windows is a problem of its own - If any at all, then Cygwin has a
chance to work, but AFAIK, at present time, nobody has ever tried to
build i386-rtems-gcc-gnat for Windows/Cygwin.

I don't think you want to run the "Ada cross-compiler" on a target
board. You want a cross-compiler to produce executables for your target
board ;).

Linux i386-rtems-gcc-gnat toolchains should be available on
ftp://ftp.oarcorp.com.
