# Disable some pointless warnings:
# 1418 is 'external definition with no prior declaration'
#    This is just pointless
# 383 is 'value copied to temporary, reference to temporary used'
#    Produced too often.
# 981 is 'operands are evaluated in unspecified order'
#    This triggers even on chained operator "<<"
# 444 is 'destructor for base class XX is not virtual'
#    Emitted on boost::noncopyable, that has no virtual
#    methods to begin with and is not a "real" base class.
# 193 is 'zero used for undefined preprocessing identifier'
#    This is common thing, and used in BOOST_WORKAROUND often.
# 530 is 'inline function XXX cannot be explicitly instantiated'
#    Obscure warning affecting Boost. No docs can be found.     
# 810 is 'conversion from X to Y may loose significant bits'
#    This is emitted even for explicit conversions
# 304 is 'access control not specified, public by default'
#    Emitted on "struct foo : whatever", which is used often in Boost.MPL
# 279 is 'controlling expression is constant'
#    Happens, in particular, on "assert(false)"
# 1419 is 'external declaration in primary source file'
#    This is just pointless
#
# It might be good idea to disable those "remark" warnings, but
# 869 (paremeter is never referenced) seems reasonable.
