Summary:                    CheckTypeSize does not work if C language is not
enabled
Description: 
If C language is not enabled, it is impossible to use the CheckTypeSize module.

Steps to Reproduce: 
This is a minimal CMakeLists.txt to show the issue:

---

cmake_minimum_required(VERSION 2.6.4)
project(test_prj CXX)
include(CheckTypeSize)
check_type_size("short" SIZEOF_SHORT)


Additional Information: 
Output:

---

-- Check size of short
CMake Error at /usr/share/cmake-2.8/Modules/CheckTypeSize.cmake:89
(try_compile):
  Unknown extension ".c" for file

    /opt/iit/build/testxx/CMakeFiles/CheckTypeSize/SIZEOF_SHORT.c

  try_compile() works only for enabled languages.  Currently these are:

    CXX

  See project() command to enable other languages.
Call Stack (most recent call first):
  /usr/share/cmake-2.8/Modules/CheckTypeSize.cmake:174 (__check_type_size_impl)
