Although its C library is lacking somewhat; UnixLib, while fat, is fast
and has excellent coverage.

Cough.  I think you'll find there is, it's just not widely used :)

I would suggest any attempts to build LuaJIT for RISC OS should be done
with a cross compiler.  Not only will it build an order of magnatude
faster, it means the build environment is more like what most Makefiles
will expect.
