Missing Library file for TouchScreenMenu

When trying to run examples for the library TouchScreenMenu, I get the following error:

TouchScreenMenuTest.ino:28:21: fatal error: cstddef.h: No such file or directory
compilation terminated.

I cannot locate this file in any of the required libraries. I tried searching for it and have seen the include for it in other Arduino sketches but can't find what library it is actually supposed to be a part of. Can anyone identify this file and what library it comes from?

What library is that? A link would be useful.

https://code.google.com/p/touch-screen-menu-library/

The file they are looking for is not in there. I haven't been able to locate cstddef.h anywhere so far and everyone assumes it is included in the library.

Sorry to bump a dead horse, but has anyone solved this? Trying to use the same library and having the same issue.

Have you tried simply deleting the #include statement? Most likely, it is not needed.
