I'm not aware of any recent discussion of this (though I haven't asked the 
people here at the WG14 meeting in London who can report decisions taken 
at particular meetings in 1985).  The syntax is within the syntax of 
preprocessing numbers, so doesn't conflict as long as there are -pedantic 
pedwarns for when 0b... preprocessing tokens are converted to tokens 
(including in #if).
