* itemdb.c/h using a static array of 32k struct item_data* entries (faster itemdb loockup and a first step to remove map_session_data->inventory_data).
* Fixed a typo in the configure script that replaced CFLAGS with CPPFLAGS when -Wno-pointer-sign is supported by the compiler. [FlavioJS] git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@11259 54d463be-8e91-2dee-dedb-b68131a5f0ec
