* This file contains dependencies that the collation run-time doesn't normally

*
* Modification history
* Date Name Comments
* 1996-1999 various members of ICU team maintained C API for collation framework
* 02/16/2001 synwee Added internal method getPrevSpecialCE
* 03/01/2001 synwee Added maxexpansion functionality.
* 03/16/2001 weiv Collation framework is rewritten in C and made UCA compliant
* 12/08/2004 grhoten Split part of ucol.cpp into ucol_res.cpp
