[Qt-creator] Creator incorrectly underlines size_t as 'not a type name'

[Danny Price]

I working on a simple C program and I'm using variables and parameters of type size_t. Although the code compiles fine, Creator insists on underlining in green every occurrence of the size_t symbol with the tooltip "'size_t' is not a typename".

I'm on OSX and size_t is defined in stddef.h which I have included. I've observed the same problem in Creator 2.0 and the latest 2.1 snapshots.

Is this a bug? Is there a workaround?
