Hi Karl,

The reasons for cross compiling are some what dubious.

I have some old systems (sparc sun4c, intel i486). The sparc does not
curently have a linux system on it so I have to cross compile everything
to get a linux system up and running on it (or by a pre-build system but 
where would the fun be if I did that).

In addition:

1) These old systems are very slow when compared to a modern system, so it
pays to build up software using a faster modern machine.

2) It tests out the configuration system. All GNU software should cross
compile as this will promote its use on any new hardware that comes along.

3) I have not been able to get a correctly working canadian cross compiler
running (using gcc-3.4.2) so I have no native compiler to compile anything

The canadian cross compiler problems are mostly me not configuring the
compiler properly. I have made working C compilers but their search paths
are all messed up. For ADA, there are bugs in the canadian cross build
including trying to use the wrong library during compilation.
