======================== main.cpp =============================================
#include "file1.h"

int main(int argc, char** argv) {
    AA i = 0;
    return 0;
}
======================== file1.h ==============================================

#ifndef FILE1_H
#define FILE1_H

#error ssssssssssssssssss
#define AA int

#endif /* FILE1_H */

===============================================================================

Scenario:
- Create project with main.cpp and file1.h
- Close IDE
- Delete old userdir and start IDE again
- Open project
- Open main.cpp file
===>

In Oracle Solaris Studio in main.cpp I see "AA is a unresolved identifier"
In NetBeans I don't see any errors in main.cpp and "AA == int"

In both cases I see "Some #include or #error directives failed." sign on project's node.

For me Oracle Solaris Studio works better in this case.
