  [Q] Pragma directive to shut up the Wefc++ messages from STL??

  Hi again!

  Is there a pragma directive or something else to shut off the 
  messages produced with warning option -Wefc++.

  Is there a plan to "correct" causes of these warnings in STL 
  in the future?

  Thanx a lot

  Miljenko
