Approved - please apply, but...

I think that it would be nicer if this logic were separated out of the 
HOSTING_CRT0 definition and put into its own variable which could then 
just be evaluated via the back-tick operator.  The reason being that you 
could then spread the definition over several lines, add some helpful 
comments and generally make it easier to read and understand.  What do 
you think ?

Cheers
