A patch file for emacs-24.3/src/canna.c, and should be contianed as a part of ports patch files

Canna (Japanese kana-kanji conversion engine) support enabled editors/emacs
port fails to compile on FreeBSD 10.0. Perhaps this will cause on 
editors/emacs23. This error seem to be a side-effect using clang.

The compile error is as follows:

canna.c:1583:17: error: non-void function 'count_char' should return a value
      [-Wreturn-type]
  if (len == 0) return;


To fix this problem, change declaration count_char() in canna.c from
static count_char(....) to static void count_char(....). The canna.c 
is created by emacs24.3canna-20130321.diff.gz which is a part of 
distfile. Change is as following:
