// Change log:
// June 20, 2001: ported by Nick Thurn to gcc 2.95.3. Kudos, Nick!!!
// May 08, 2002: replaced const_iterator with iterator so that self-modifying
// ProductCreators are supported. Also, added a throw()
// spec to what(). Credit due to Jason Fischl.
// February 2, 2003: fixed dependent names - credit due to Rani Sharoni
// March 4, 2003: fixed dependent names - credit due to Ruslan Zasukhin and CW 8.3
// July 26, 2005: parameter support by Peter K<>mmel
