Log Message:
Update ja-FreeWnn-lib and ja-FreeWnn-server to 1.11alpha23,
per FreeWnn-1.1.1-a023 release.

Upstream changelog in the release note:
 http://osdn.jp/projects/freewnn/releases/63271

Basically, This alhpa version is a snapshot release.

Main changes:

 * Merge modificaion used in OpenSUSE packages by new member,
   Mitsutoshi NAKANO. Added explicit function prototype and cast in
   many places, so we reduced unpredictable effect on 64bit environment.
 * As a consequence of this change, #define of WNN_CREATE / WNN_NO_CREATE
   in jl_dic_create() is also changed. We believe no change is needed
   for client build, but please report if you have problems.
 * Exit status of jserver changed on receiving some signals (ex. SIGTERM).
   (Not well documented.)
 * Fixed problem for parallel build (ex. make -jXX) on pubdic+.
