++	Fix compilation error with GCC 6
++
++	* include/thai/thctype.h (_th_bitmsk):
++	  - Use unsigned int instead of unsigned short for bitmask base,
++	    as GCC 6 takes ~0 as -1 for unsigned short,
++	    and causes compilation error for scim-thai.
++
++	Thanks Martin Michlmayr for the report via Debian #811690
++	http://bugs.debian.org/811690
++
++2016-01-20  Theppitak Karoonboonyanan  <theppitak@gmail.com>
++
+ 	* configure.ac: Post-release version suffix added.
