Compile it with gcc -Wall -o nantest nantest.c -lm and run it. It tests NAN anf INFINITY values with isinf() and isnan(). The expected output is: ================== $ ./nantest computed NAN 1 0 computed INFINITY 0 1 ================== Instead of "computed", NetBSD/x86-64 prints "defined" but the test results are the same as under Linux/x86-64.
