3194	compiler warnings in VC9	kfriddile@…	Daryle Walker	"The following code under VC9 with warning level 4 produces the warnings below. Warnings are not allowed on my project, and rather than wrapping boost includes with a #pragma directive, I'd rather these warnings just be suppressed in the code that's causing them.

boost::uint32_t GenerateChecksum( const char* data, size_t length )
{
  boost::crc_32_type computer;

  computer = std::for_each( data,
                            data + length,
                            computer );

  return computer();
}
