I don't have a general answer to your question, but I did find a
bug in AIX 3.1 sprintf() which is causing the specific test case
to fail -- the number emited by the sprintf should be 0.12345678901234548.

I'll open a defect report to fix it in the next release.  Please call in
an APAR to get the fix before then.
