// Disable warning for "extra qualifications" here.  One of the boost log
// headers triggers this warning.  Note: use of disable pragma here is
// intentional - attempts to use push/pop as you ordinarily should just
// yielded a gripe from the MS tools that "warning number '4596' is not a
// valid compiler warning". re-enabling the warning after the include
// fails in the same way, so just leave it disabled for the rest of the
// file.  This is safe, since the warning can only trigger inside a class
// declaration, of which there are none in this file.
