OK, I applied the patch. You might want to massage the comment a bit, and 
probably extend the condition to include GCC 3.4 as well.

I also tried using BOOST_STATIC_ASSERT(false) but I also get the compile 
error, so I have no other idea besides turning the compile time error into 
a link time error.

BTW, I think there is no test (expected-to-fail) which actually checks that 
your helpful catch-all code is actually working as expected. But now you 
would need two tests anyway, depending on the compiler. I don't know if 
this is supported by Boost.Build out of the box.
