    Disable gcc 33 on OpenBSD because it crashes CPack by default.
    
    Make sure no one tries to use gcc 33 based tools to build CMake.
    This is because a cpack test failed with a crash.  The crash
    seems to be caused by the stack checking code on by default in
    OpenBSD.  The crash is in some stl code.  The problem is fixed
    with newer gcc compilers on OpenBSD.
