xtl not 64-bit compliant

[Angus Leeming <a.leeming@ic.ac.uk>]

The test programs "xdr" and "giop" in xtl-1.3/examples/tests
fail because xdr.h and giop.h make assumptions about the
size of the intrinsic data types. I'll make a patch to sort
this out, but thought you might be interested in the
results of a small program on an Alpha machine.
