Re: [boost] Lots of warnings

From: Paul A Bristow (pbristow_at_[hidden])

I've seen similar and supressed with a bracket of 

#if defined (BOOST_MSVC)
#  pragma warning(push)
#  pragma warning(disable: 4512) // "assignment operator could not be generated."
#  pragma warning(disable: 4127) // "conditional expression is constant."
#  pragma warning(disable: 4100) // "'boost_parameter_enabler_argument' : unreferenced formal parameter"
#endif

your includes

your code....

#if defined (BOOST_MSVC)
#  pragma warning(pop)
#endif

But it really would be nice if *All* Boost code could have warnings suppressed properly.  The situation is imporoving, but we have
some way to go.

The impression a blizzard of pages and pages and pages of these warnings gives is really bad :-((
