You do not need these defines, and you do not need to redefine typeof
as __typeof__ for SunProCC. You only need to pass the correct flags to
the Sun C++ compiler:

[steleman_at_darthvader][~/tmp][04/04/2012 19:00:53][1104]>> cat ./typeof.cc
#include <iostream>

int
main (int argc, char* argv[])
{
    typeof (typeof (char*)[4]) y0;
    typeof (int*) y1[4];
    char* y2[4];
    int* y3[4];

    std::cerr << argv[0] << std::endl;

    return 0;
}
