Yep. I didn't think of this. If we do so, it's not necessary to have
16*16 defines. We could have 16 #defines to zero in
select_compiler_config.hpp, and then, in each compiler-config file:

#undef BOOST_THIS_COMPILER
#define BOOST_THIS_COMPILER version

This reduces the number of definitions from 16*16 to 16+16. Ok, I know
you already thought to this... it was just to prevent possible
objections :)

Yes. Ok with me.

Yes, Jonathan makes a good point too, in this regard.

Genny.
