I just get back to this...

The idea is basically to do anything that issues a warning but not an error.
The following generates a warning both on BCC and Comeau online: ( (signed
int)(-1) < (unsigned int)(1) )
I've updated the macros to use this as the triggering diagnostic.New header
attached here.

If the trick is working on most of the boost target compilers, I can polish
it up and write a doc so it can be included in /utility or /detail.
