We already have BOOST_WORKAROUND. What I can do is provide a
BOOST_WORKAROUND that will use an enum if the datatype is not too wide.
Simple but effective!

historical note: The reason I brought this up was because Mathias Troyer
  asked me to remove the BOOST_NO_INCLASS_MEMBER_INITIALIZATION in the
config for vacpp version 6. And indeed, vacpp can handle the
initialization but does not comply with the DR (so one can argue if
Defining it however caused a problem in the random library however
(Mathias can you recall what exactly happened and why).

Next, should'nt it be a good idea to mention the policy on the out of
line definition on
(I'm willing to do it but a language lawyer among us should probably
best revise it before I commit it).
