The latter. We of course can't include in the windows binaries all the
binaries for all the existing embedded development architectures.
The powerpc port is done: the changes you might need are related to
the operating system you run. Basically you need:
*) a POSIX thread implementation
*) a glib port
*) a libgc port
*) for the jit port the things that matter are:
1) the call convention (we already handle the Linux-like call conv and
the AIX/MacOSX one)
2) the signal handler OS-specific code (look at the bottom of
mini/exceptions-ppc.c)
3) if the OS uses function descriptors there is some additional work,
but I don't think embedded ppc oses use that abomination.
