(Speaking boost-wide, I note that

warning C4127: conditional expression is constant

is very common and I cannot conceive of when it could possibly be helpful.

It is the sort of thing that is /very/ useful in the first pass of compiling ones own code - but is a real pain for libraries like boost that need to choose between implementations depending on platform characteristics.

Also

warning C4800: 'int' : forcing value to bool 'true' or 'false' (performance warning)

Yup. I *hate* that one. I really wish they would remove it.

Should a 'certain to be included' boost file 'globally' disable at least these two warnings? Insert into boost config? )

PS MSVC 8.0 notes:

Conversion wizard runs fine with no errors. (some 3 conversion warnings which look unimportant).

There are very many warnings like:

i:\boost-06-01-13-0500\boost\test\results_collector.hpp(79) : warning C4275: non dll-interface class 'boost::noncopyable_::noncopyable' used as base for dll-interface class 'boost::unit_test::singleton<Derived>' with [ Derived=boost::unit_test::results_collector_t ] i:\boost-06-01-13-0500\boost\noncopyable.hpp(22) : see declaration of 'boost::noncopyable_::noncopyable'

Should this be disabled somewhere too?
