           Summary: glew.h parsing breaks on #include <GL/glu.h>
           Product: kdevelop
           Version: git master
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Language Support: CPP
        AssignedTo: kdevelop-bugs@kdevelop.org
        ReportedBy: l.jirkovsky@gmail.com


Version:           git master (using KDE 4.7.2) 
OS:                Linux

When using glew in a project, many of the functions defined here are marked
with the "Declaration not found" problem.

However when I remove the following code from the glew.h, the declaration for
the functions is found (actually they are using macros to query the extension
functions):

#ifndef GLEW_NO_GLU
#  if defined(__APPLE__) && defined(__MACH__)
#    include <OpenGL/glu.h>
#  else
#    include <GL/glu.h>
#  endif
#endif

Using
#define GLEW_NO_GLU
#include <glew.h>
instead of simply including glew.h doesn't work.

Reproducible: Always

Steps to Reproduce:
create file containing the following code:

#include <GL/glew.h>

int main() {
  glGenBuffers(1, 1);
  return 0;
}

The problem toolview will say that the declaration for glGenBuffers() was not
found.

Now try to remove the "#ifndef GLEW_NO_GLU" code from glew.h. The declaration
for the glGenBuffers() is found.

Actual Results:  
The declaration is found only with "#include <GL/glu.h>" removed.

Expected Results:  
The declaration is found with the original glew.h header.
