I'm not able to reproduce that with cygwin-gcc-4.3.4 
and -Wall -Wextra -pedantic and either Boost-1.44 or 1.43, do you have a 
minimal test case?

It also looks to me that maybe BOOST_NO_INCLASS_MEMBER_INITIALIZATION is 
defined given that the warning talks about enum's - however this should 
never be the case with gcc.

Confused yours, John.
