----------------
Minor point, we may want to use < 903000 for these tests instead (corresponding to the 9.3 release).  It's a minor point, but I think more accurately reflects the intent of the test.

For example, a hypothetical 9.2.1 point release would still lack -m32 support in headers, but would have a __FreeBSD_version higher then 902001.
