Thanks very much for that.

Here's the attached test code. 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.
