Summary:                    CheckTypeSize doesn't behave as documented in daily
build
Description: 
According to the documentation of CheckTypeSize ...

If the BUILTIN_TYPES_ONLY option is not given, the macro checks for headers
<sys/types.h>, <stdint.h>, and <stddef.h>, and saves results in
HAVE_SYS_TYPES_H, HAVE_STDINT_H, and HAVE_STDDEF_H. The type size check
automatically includes the available headers, thus supporting checks of types
defined in the headers.

...

The above behavior works in all versions of cmake including the current daily
build 2.8.12.20140108-gc5c24.

However if there is a CHECK_TYPE_SIZE invocation with BUILTIN_TYPES_ONLY option,
further CHECK_TYPE_SIZE without BUILTIN_TYPES_ONLY fails (does not
detect/include the required headers <sys/types.h>, <stdint.h>, and <stddef.h>).
This is observed in the daily builds (tested on 2.8.12.20140108-gc5c24).




Steps to Reproduce: 
An example CMakeLists.txt attached.
