The test for lib.string.compare is here: http://people.apache.org/~antonp/stdcxx05022006b/
Also there are required difference for 21.strings.cpp and 21.strings.h files. The change log: 2006-05-02 Anton Pevtsov <[EMAIL PROTECTED]> * 21.strings.h (MemberId): Added new element for compare. (OverloadId): Added new enum elements for compare overloads. * 21.strings.cpp (_rw_setvars): Added support for compare overloads. With best wishes, Anton Pevtsov.
