Ah, you are right. It's our version.

So, do a find_path() for libintl.h, then push the *_REQUIRED_* variables 
(there are macros for that), then add the path from find_path() to the 
required includes, then do the tests, then restore the *_REQUIRED_* variables 
using pop.
Maybe the check_include_files() can also simply be replaced by a find_path().
