True.  Mark, can you run a compilation after replacing
<ql/utilities/null.hpp> with the one I'm attaching?  You'll get a number
of errors saying that Null<T> is undefined for a few types.  I'm
interested in knowing for what built-in type(s) it fails.

Also, is there any #define we can check to see if we're compiling for 64
bits?

Luigi

P.S. re the other 64-bit fix (atoi vs lexical_cast): it compiles, but it
changes behavior.  If the input is, say, "foo", lexical_cast raises an
exception, whereas atoi quietly returns 0.  I'd prefer a solution that
keeps the old behavior.
