On FreeBSD 8.1 with boost 1.43 and gcc 4.2.1 we have lots of warnings
like:
...

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.
These warnings appear by just including lexical_cast.hpp (see below). Any
ideas where the warnings come from?
Tomorrow I'll try to use another gcc version and/or another boost version.
