OK. Time profiling isn't supported and I haven't tested the memprof grade
yet.  At the moment I am trying to get the compiler to pass all the
tests in the hlc.gc and none.gc grades as they are what are important to
MC.

I can't remember exactly what the problem was, but it was in a similar
vein to all the other problems I have fixed.  I will post the details
when I look at it next.

It *should* but I haven't tested it yet.

So in summary I have just added the grades which I know bootstrap.  When
I get a chance I will start testing the other grades and then generalise
the configure script.
