A macro allows you to do conditional compilation while an integral 
constant of any form will not.  In general, such "version macros" are 
only useful in that they allow you to do conditional compilation.  
Other uses are "fluff" (such as printing version numbers) and 
wouldn't warrant the inclusion into the Boost headers.
