It means that someone needs to try it, so we can actually make progress 
on fixing any problems, if there are any.

This is likely.

GCC 4.1 is a complete move away from AOF.  None of the toolchain
produces or understands AOF or AOF-style assembler.  The single
exception is the ELF executable to AOF converter which will work
for static binaries.  This could be used as an interim during
the final packaging step, until the shared library situation is
perhaps more mature.  That is, we should probably stick to
static binaries just for the moment.  This is easy in the
current framework.

I don't know that there's anything additional (apart from minor
toolchain differences) than what you're doing already.  Almost
everything you've done is applicable.  One exception is SDL
which requires some RISC OS-specific gas format assembly
(converted from the AOF version).

I don't know the exact versioning of the top of my head, but if the
current UnixLib requires this, then I don't see any problem.
