Wow - gnulib's version of strtod really IS inaccurate. The buildbot is still showing failures, since 5 * pow (10.0, -1) != 0.5. Any suggestions on how to make this test pass? Would it be acceptable (for now) to just check that the result is within 1 or 2 ULP of the correct answer? - -- Don't work too hard, make some time for fun as well!
