This is technically with patchlevel 21401 5.9.0. I note that there are more
failures when using -Dusemorebits (as in, including both -Duselongdouble and
-Duse64bitint). The pattern of the failures for 'pow.t' is rather
consistently that the value resulting is just _slightly_ off (more off the
larger the values being dealt with, which makes sense); it shows up at lower
numbers when using 64-bit-ints. I would think this was just a matter of the
pow.t tests needing to have an epsilon greater than 0, but the Math::BigInt
stuff indicates otherwise (this is from the first machine, with just
-Duselongdouble; -Dusemorebits gives the same results for Math::BigInt):

# Test 2140 got: '1' (../lib/Math/BigInt/t//bigintpm.inc at line 194 fail #1177)
#      Expected: '2'
# Test 2146 got: '2' (../lib/Math/BigInt/t//bigintpm.inc at line 194 fail #1180)

Tels says that this is probably because BigInt uses pow internally. Tels,
are the above failures all with _root?
