'stdio.h' not found

[sweeney]

I have noticed in Codelite 13.0.x and 14.0.x on Windows 10, the code editor will complain the C standard headers files like stdio.h are cannot be found when working on a C program, but has no issues with C++ standard headers like iostream when working a C++ program.
It seems to make no difference which whether cygwin or mingw compiler is selected and the source code compiles fine without issues. On FreeBSD/clang setup I have, the issue is not present.
Any ideas why this would be the case?

I find it funny how codelite knows about the standard printf function and complains about stdio.h not being included, but cannot find the stdio.h file specified at the top of the file...
