Can someone clear this up for me? My reading of 23.1.3 of the April WP indicated that operator == should not be required by the associative containers. I havent' checked the September WP, but I don't expect this non-requirement to have changed. When I submitted a bug report to ObjectSpace against version 1.1.0 of the library, I was told that they simply hadn't caught up with the WP yet. The document accompanying version 1.2 of the library also specifies the same requirement. Looks like they still haven't caught up with the WP. One of the few annoying inconsistencies in an otherwise very good implementation of STL. -- Ajay Kamdar | Email: ajay@lehman.com | Standard Disclaimer Lehman Brothers | Phone: (201) 524-5048 | [ comp.std.c++ is moderated.
